...and position 5

Just a heads up for anyone replacing their mounts with poly instead of rubber. I just did this and only a few of the stock length bolts worked. The poly mounts will require longer than stock bolts in almost every position. I think I was able to only use 2 or 4 stock length bolts, I can't remember for sure.

That's interesting...every poly set I've ever seen had 'thinner' bushings.

Thanks for posting up what you've run into.

vtblazer · 09-16-2009, 11:23 AM

Remaining parts to each position aside from the rubber body mounts.

vtblazer · 09-16-2009, 11:24 AM

...and position 5.

**lks dcvn** · 09-16-2009, 11:52 AM

where did you get the kit from?

EDIT - After Googling the PN#s looks like the LMC numbers...

Twisted78SS · 09-16-2009, 11:56 AM

Thanks! good info that always seems to be overlooked..

71jimmy · 09-16-2009, 04:24 PM

Great stuff VT.

Moderators please post to FAQ section.

vtblazer · 09-16-2009, 05:20 PM

The set I got from Tim is what I would consider to be "complete".

There are other vendors out there selling...lets just say "not so complete" sets.

Talked with another blazer guy who just received one of those 'other' sets and it was missing these items:
* the square washers for the core support
* the 7/16 core support bolts
* ALL 4 concentric washers
* and both position #2 bolts were M.I.A.

At a premium price too.

**lks dcvn** · 09-16-2009, 05:37 PM

What does the kit from Tim cost - I checked his site - but couldn't locate it in the product listings.

Thx for posting this (BTW) -

Burt4x4 · 09-16-2009, 05:41 PM

You're making it too easy for rookies

We had to bleed,sweat & cry to get that far ahead in replacing them. I probly made 5 different trips to the bolt store to do mine hahaha

I can't remember what I paid Tim, it was over 6 months ago and I'm sure prices have gone up.

The incomplete kit in the pic was over $200.00 though.

Yeah, newbs have it to easy now for sure and still they don't bother to look anything up.

Sorry bud, tube doors went with the blue blazer.
Want me to build a pair for ya?

vtblazer · 11-24-2009, 07:48 AM

Bump incase some missed this and are wondering.

Critter · 11-24-2009, 09:00 AM

I'm wondering why it isn't in the FAQ section?

Glad you brought this back ttt.

I replaced mine a couple years ago with a poly kit but I didn't get the concentric washers. Did I screw up? Why does it need the concentric washers? I have everything pretty torn apart at the moment, should I add them?

They say a picture is worth a thousand words.

zammer · 11-24-2009, 09:47 AM

Thanks for the great info!

Now... is the body mount kit the same for the 2wd and the 4x4 blazers??

I am having trouble finding a kit that says it is compatible with the 2wd blazer..

thanks

So the answer is "Yes, I should get them" looks like it keeps the body from shifting from side to side. Thanks Kurt, as usual you have made me realize that I need something that I didn't even know existed.

...well I'll take that as a 'good' thing.

The factory didn't use the washers but it seems like a good idea, can't hurt.

**lks dcvn** · 11-24-2009, 11:17 AM

It (offset washer) basically acts to lock the carriage bolt to the floor so you can tighten them down without welding the head to the bed.

k5keith · 02-06-2010, 12:12 PM

VT what grade are those 3/8 bolts ?

highrpm · 02-07-2010, 02:36 PM
