1995 G30 van conversion, I have Bilstein shocks on the rear, but have a problem with the top mount that was happening even before installing them . At first the drivers side was broken when I got the van, now both sides are broken and lost (the last one was lost probably somewhere in Baton Rouge)

First you might know the anatomy of the rear shocks, I am missing parts. On my g30 and I think all G vans in the rear the way the top of the shock is bolted on is a long bolt like 7.5 inches goes though a hole in the rear frame from the outside (tire side) and then I thought it went through some kind of bracket or welded on metal tube and then into the shock. In looking on this forum I found a diagram and a pic (the pic is not of my van but shows what the part should look like. My van still has the bolt holes intact and not messed up or enlarged like in the bottom pic. [Linked Image]

When I bought the van I noticed the drivers side shock was disconnected at the top. I asked a mechanic to reweld the mount that broke from the "frame" , when I picked up the car I though it was ok, because I was in a rush but then later noticed the shock was crooked and the upper pitched a bit outward because the shock rested up outward to the frame. I realized they did not weld any spacer or mount but just put a bolt through the hole so the top is right against the hole in the frame. It was probably the case that the original mount was not there and lost on the road and they could not find or order a new mount. So they just grabbed a heavy duty bolt and did their best without the space. But that bolt did hold.

But because I wanted the shock straight I tried to add a longer bolt with some larger nuts as spacers between the frame and the shock to make the shock straight. first I just could find a grade 5 bolt and it snapped. Then I used a black grade 8 bolt from my local parts store they happened to find one in the back. And it bent and the nut came off so the shock was resting against the rear floor but still on the bent bolt. So then I found a grade 8 steel zinc coated bolt and more spacers and after 600 miles that also snapped.

So I am a bit confused what to do. These are 1/2 diameter, bolts the larges possible size can fit in the hole, but for this diameter I cannot find any long enough grade 9 or grade 10 bolts. I can find grade 8 bolts only 7 or 8 inches. I am able to find fully threaded bolts so I can forget about spacers or maybe get something welded to the frame? Is there a replacement bracket or tube that one can weld?

Otherwise I think going with the first solution the auto mechanic did was to just bolt the shock against the frame without any spacers or nuts because then it is stronger. So maybe doing it that way even though the have the shocks will be slightly pitched is not too bad? I was thinking over time it would damage the shocks but not sure. It really makes the bottom of the shock where it mounts to the bock bracket at a strange crooked angle that might destroy the shock bolt bushings in the shocks, both on the bottom and on top. Because the pitched angle makes the bolt so crooked in the shock.

Has anyone else had this problem? did you weld a new tube or something to make the bolt stronger?

Any advice appreciated.

Hey Scoob,

So. Something ain't right. I'll look at my 1996. I have a Parts manual for my 1990 too.
Breakfast and feed the herd, then I'm out front. I'll look and see if there is a mount you are missing.

So. I do know, on my 1990, the first set of Bilstein's that Summit sent were way too short. I called the guy from Summit, he knew exactly why. "Dually application (capable) axle" Full floating with the protruding hub. Those fit. Might check your GVWR. I'll see.

I think the 1990 is #9200. 6400 empty. 1996 EXT Cargo same GVWR, 9200, but the unladen weight is only #5500 Compared to #6400. The 900 pound difference is a 454 and a Beauville interior. lol.

Comp9 will give you ALL the RPO production build codes, similar builds, builds numbers, etc. Sample on my signature for the 1996 G30 EXT vans, that do exist.

The RPO codes on a label. are inside the glovebox on the doghouse, Comp9 decodes all the codes, will give you your vehicle specific suspension capacity as built.

With your conversion, that's a lotta weight Scoob, well over 1000 pounds. Van on!

Hey Scoob, the exploded diagram shows the #1 Mount inserts into the Subframe and the shock through bolts through that tube through the Subframe rails. I know what SwimShop 4x vans would do. Make a better mount. Zzzztt.
Get new bushings, sleeves, and a better bolt. Washers and Deer nuts!

I haven't crawled underneath my Vans yet today. It could still happen. I need a CHP mirror on a stick.

I admit I was a slacker today, but I did feed and water the herd, plus made Bfast, lunch and Ding! Dinner. Van On.

Plus, ran all over town searching hardware stores and the Chevy dealer for Van specific letter code parts/key blanks, then got groceries. G'day! Not over yet!

Looks like just a sleeved long bolt, if you had to, you could use all thread with a steel tube slid over it.
