thanks

It is 3-6" x 14-0" and about 30" tall when bolted down to the floor. The table is made from 3.5"x3.5" 3/8" wall tube with a 3" x 1/2" plate welded to the top of the tubes that has been drilled and tapped every 3" OC.

I have a simple but effective laser system from my days of building high rise buildings that I use for leveling the table (with in .015") and also use for dead center of the table during builds. So far this table has worked out great and during non use I have 4 6" casters that bolt to the legs and allow me to move it out of the bay for other work.

Here is a bonus pic of a 1/2 scale project I have been messing around with for my son. No more info will be given about it so don't ask

Looks cool. Could you be persuaded to post a build thread in "Alternate Tinkerings"?

TonyJohnson · 09-20-2009, 03:26 PM

Very cool.

fbird68 · 09-29-2009, 11:45 PM

Hey Kevin,
I read through your whole thread here in the last couple days. You have some talent my man.
I also followed your link to the T-bird IRS install because I am planning to do the same thing to my 51 Merc PU. Thanks a lot for the great pics and explanation of how you did yours.

Spray-Bomb · 09-30-2009, 01:28 AM

Is it just me, or are the rear wheels not centered front to back ???

They look kinda far back to me, but it could just be the angle I guess

Looks sweet bro !!!!!

ccreddell · 10-14-2009, 07:54 PM

Fazel, Im sure Kevin will jump in here too, but I do know the answer for you. First of all, on a dropmember, the geometry is tweeked to match the different wheelbase and roll center (among other things) of the truck vs the original vette. Its also a bolt on proposition. I know that there are those that fab up a crossmember to mount the vette components (never seen anyone use the stock one) but normally they dont try to re-engineer the geometry to match the truck. This is not optimum, but it haws been done. Of course Ive also seen guys bolt the rear-end to the frame with U-bolts and call it a lowering job-to me its worth the money to do it right. That may also be the reason I dont have one yet..........

Rokcrln · 10-15-2009, 10:09 AM

That is correct as well as the track width has been narrowed I think 2-4" for the trucks. This allows for more turn radius when lowered with larger tires. But if you want concrete info send a PM to Nate Porter and ask him, he will be glad to give you any info you may want on the ability of using a stock cross member.

Dave Reed · 10-15-2009, 11:05 AM

Speaking of PB. When will his new site be up? Not that I needed anything, but I did want to see what he had.

ccreddell · 10-15-2009, 11:18 PM

Kevin, if I'm not mistaken, the C4 dropmember doesnt narrow the 'Vette' width, although a Vette has a little narrower track than the truck. Otherwise the stock rack wouldnt work. The regular dropmember does narrow the width of the truck by design.

Rokcrln · 10-16-2009, 10:41 AM

The stock rack doesn't work and is replaced by a widened MII rack. I think it is still narrowed up but about 2" less then the regular DM but I may be incorrect about width. But the rack does need to be replaced that I know.

I guess I was mistaken then. Ive been reading everything I can on the DMs and I could have sworn the C4 DM used the stock Vette rack. I do know that the regular DM is narrowed 2" and uses a widened MII rack, but I was under the impression that the Vette was already a bit narrower in stock form.

Originally, it did use the stock C4 R&P. Now it uses a MII unit.

That's very cool...will we at least see the finished product.......please

BlueJeep · 10-16-2009, 12:08 PM

Hmmm....no build thread... Is this something that will be commercially available in the future?

And if so, will it be available in a 2 seater (2 y/o twin boys)?

KLINGER · 10-16-2009, 12:45 PM

is that the t-bird irs i spot? I WOULD LOVE to see the finished write up on this as i am planning on doing the same to mine.

ccreddell · 10-16-2009, 06:42 PM

yeah, I should have said 2" per side.

Frizzle Fry · 10-17-2009, 12:42 AM

and an unmodified MII rack.

Rokcrln · 11-11-2009, 04:47 PM

Ok bare with me as my ADD kicks in today! I have customer trucks to be working on but my mind is wondering so I wanted to get the evil thoughts out of my head.

First was the exhaust and a friend of mine just picked up a 99 F-body LS motor complete for a 45 chevy PU he is building and the first thing he bought for it were headers. That left his stock manifolds sitting their and after seeing Hart_Rod's Donkey build and how well his stockers fit I drove down to my friends and picked them up for a test fit. Rob is running the stock front cross-member and I have a DM C4 in this so I was not sure how it would work. Well it works great and for the price of free I do believe their are just the one's I was looking for. My steering will work out great as well and with these DM that is a big plus! So here are a few pic's.

[IMG]

[/IMG]

Then I decided to lift the Tahoe up so I could take a few measurements to make sure an oil pan I just ordered for the 5.3L would work with the drop member (and it will) but I had to wait for the elect comps to charge up the system before I could lift it (been sitting for a few weeks untouched) and the system was empty.

So this got me thinking of how I would like to have an On Board Air (OBA) system on the motor as well as the elect (for back ups) pumps. See how ADD really gets in the way of work! So out came the wrenches and about 30 min later I had the system designed in my head and laid out on the motor. I removed the tensioner and put the ALT. over on that side and with a very simple bracket it will mount and line up real well. Then over were the ALT. was I will mount a small compressor (this one is off my Rock crawler and has worked great for years with a small mount of oiling and puts out close to what the York's put out since a york will not fit. This one is off a 5.0 mustang if I remember right and with a bracket or two should mount up just fine as well and the pulley matches what is on the motor already. So for a tensioner I will use the old ALT. mounting bracket for the solid base and build an adjustable rod that will hook from their over to the ALT. and allow me to tighten the belt. It will be a fancy adjuster rod since I need to clear the radiator hose inlet.

Now after doing all this I have never looked to see if their was a kit already for this and I have just been wasting my time or not. So if you know of one or have a pic of something out their please lets see it.

**Hart_Rod** · 11-11-2009, 08:45 PM

ADD can be a good thing,

. I'm glad the manifolds worked out. Do you think the that compressor would work with my Magnacharger setup?

Rokcrln · 11-11-2009, 09:17 PM

I don't know, I would need a good front shot with the belt on to see. I will have mine done by morning so I will post up a few pics when done. I have seen a company out their that sells a kit to mount a York style off the side of the ALT bracket but it looks terrible and runs off a single small V-belt. My set up will look real clean and uses a 6 rib 7/8 belt.

LFD Inc.

**Hart_Rod** · 11-11-2009, 09:31 PM

Looking forward to seeing the final setup. Here's a front shot.

Rokcrln · 11-12-2009, 12:40 AM

Now I need a shot of the ALT and the clearance to the blower. That is were it will be tight.

I got a little bit ahead of my self and cut off a mounting ear on the factory ALT. bracket so I would have clearance for the A/C pump only to realize I did not have the coil packs mounted and the A/C pump hit them

So now I get to weld it back in place in order to make a nice clean belt adjuster that will use that stock mounting tab. I have all the clearances worked out now so I just need to have a full day to build it all and order a few hiem joints for adjusters. With the larger diameter pulley on the A/C pump compared to the small ALT . pulley caused a bit of a clearance problem that was solved by sliding the A/C pump forward .045 and milling the head of the bolt off by .045 to get just enough room so they will not touch each other.

So in the morning I will Tig the ear I cut off back on and make the new ALT mounting bracket then find a belt that fits. You can also see their is about 1/4" of free space between the belt and the lower Radiator hose. How do you like how well the rear of the A/C pump fits around the coil packs and the end of the fuel rail? Just like it was meant to be!
