Trailing arm question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Solver · 11-07-2005, 01:01 AM

recently I redid a frame and had a couple of trailing arms left over .One was beyond repair but the other is pretty decent except it is seperated.
I sandblasted it down,drilled out all the rivets today and removed all the crap in between the 2 halves.
Drilled the holes bigger for some grade 8 bolts and Painted it with some por15. My question is does there need to be something sandwiched in between the 2 halves or can I just bolt it together as is.

Rick I believe there were 10 rivits to drill.
took less than 1 hour. I got the grade 8's at a farm and home store called Bomgaars here. They sell them by the pound here. I think they were $3-$4 a pound. Since I only need a few the cost was minimal. Can't really tell you exact price as I also picked up some bigger grade 8's to bolt the whole front cross member on the front of the frame also.I would assume that the auto parts stores would sell them also but I find it cheaper to buy where the farmers do!!

ttt for the original question

I don't believe anything goes in between them. The ones I bought don't appear to have anything in the middle.

ONly thing I have ever seen in there is rust.
if you can't find grade 8...grade 5 is more than strong enough. A rivit is grade 3 or something pathetic like that.

I've bought grade 8 bolts at Lowe's in the fastener aisle.
