My 50th Suspension change - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Bob 68327 · 03-20-2011, 11:12 PM

Well the old suspension has served me well for 10 years but it's time for an update . in the pics that follow you will see the old crossmember is out to get repalced with an 83 front end including drop spindles and disk brakes it will also be 5on 4 3/4 bolt pattern front and rear . The rear is a car rear end that is 4'' narrower than the stock one . there is also a teaser pic of the new wheels . I will show how I achieved the the new bolt pattern on the front soon till then enjoy the pics..

Bob 68327 · 03-20-2011, 11:13 PM

By changing the crossmember, does that mean the motor will be mounted in a different location than stock? I am asking because I mounted a 86 control arms on my 69 and am having header issues with them hitting rear of bottom control arms. I did not change crossmember though. Thanks! Chad

Bob 68327 · 03-23-2011, 06:37 PM

Motor will be in stock location . can't see any header issues with it yet.

**lolife99** · 03-27-2011, 11:51 PM

Looks great!
Did you change the M/C and add a disc/drum proportioning valve?

Bob 68327 · 03-27-2011, 11:57 PM

same M/C add disk/drum prop valve Upon some reading the M/C is supposed to work, after bleeding I have good pedal so we will see if it works . Figured it was worth a shot kinda on a low budget but if it doesn't work right it will get changed .

**lolife99** · 03-28-2011, 12:01 AM

I think you could make some money selling these rotors with a 5x4.75 bolt pattern.
There seems to be interest by members looking to get this pattern on these old trucks.

I assume you have to turn the hub diameter down to match your "jig" that you made?

Bob 68327 · 03-28-2011, 06:15 AM

Nope the hub diameter stays the same the jig fits over it very tightly .

Bob 68327 · 04-01-2011, 11:15 PM

The motors back in and a few hours away from running and driving going to have to order some new springs front is about 3'' too tall no pictures tonight but when I get it out for a test drive I will take some more . kinda excited to drive it and see how well it stops now .

Frkypunk70 · 04-01-2011, 11:35 PM

Like the new wheels, but hate to say it was one of my favorite trucks with the rallies. I was also surprised you did'nt go with a cop caprice rear or impala ss. Either way still a forum favorite.

I know I liked the rallys but it was time for a change as far as the rear end goes I got a great deal on it and it's the width I wanted so we will see how strong it is . I'm sure it will be strong enough I have seen a few GN's with big turbos and slicks running stock rears with no problem .

DINS 1 · 04-05-2011, 08:04 PM

LOOKS GREAT Cant wait to see the rear wheels on the narrow rear. I hope the rear end holds up at least for the first few launches.

It will be fine .... Thanks Buddy......

Bob 68327 · 04-10-2011, 10:24 PM

Got all the bugs out of the front end and put it on the alignment rack today and finally went for a ride .... Now it's time for the rear end to come out .. More pics comming soon....

**lolife99** · 04-10-2011, 10:33 PM

How big of a rear tire are you going to use?

You gonna have it at Des Moine in July for the Goodguys show?

Rear tire unknown at the moment I haven't even figured how wide the rear wheels will be I will get the rear end in and do some very carefull measuring then order the new rear wheels and hopefully I can afford tires after that .. My cash flow is very low at the moment so hopefully that starts looking up . Planning to be at Good guys show unless I cant afford to put tires on it have to see....

**thelonerife** · 04-10-2011, 10:57 PM

awesome! I wish my truck were 4 3/4'' also. there are a lot more wheel options. Great job!

Thank You .. I might not have changed the bolt pattern but i'm putting a car rear end in it and wanted it to match I have a lot of time in the front rotors but they came out nice..

Bob 68327 · 04-17-2011, 10:41 PM

The rear end is in it now to fab up shock mounts and figure out tire size so I can spend some more money I don't have

Here is a teaser pic of a wheel mocked up thanks to my buddy who let me steal it off his truck ..Sorry they are crappy cell phone pics for now... Bob

DINS 1 · 04-18-2011, 06:56 AM
