need info on bolts - The 1947 - Present Chevrolet & GMC Truck Message Board Network

mcmlxix · 12-12-2003, 05:49 PM

I have all new moog parts for the front end. I want to find the lower control arm bolts locally before I tear into it. Does anyone have the dimensions? Are the OE Grade 8? What about the perches that hold the lower control arm in place? Its hard to tell. What about the Gm part numbers for them? And does any one with an interchange manual know if they were use in other trucks?
This is all for a 1971 C/10 SWB with power steering.

as for the bolts i cant find sizes but LMC sells them for the trucks for upper and lower control arms

The perches for the lower arms are riveted to the crossmember. If they are not damaged, there should not be any reason to replace them.

Well I spoke to a few dealerships today. I ended up buying one U-bolt. They raped me for $7.35. They invoiced it uner part number 345970. When I got back to work a made a few calls. The other dealer said that part number fits 73-96 C1500 trucks and the G-Van. Ther computer didnt go back any further ...

I did a search on the board. I came up with one post in the 73-87 board matching that part number for $3.83 each. They were looking for them for an 80 C10. Now I am wondering if its the right bolt.

I will try and compre it to one on the truck tomorrow(provided it's not snowing)

If any one has access to a dealership, please verify this part number and if it will fit my 71 C10.

Also, if you can get them cheap, let me know what 4 with shipping to 10310 will cost. The dealers around me a jerks and a rip off!

Thanks
Rich

I can get 4 of them for 5.16 each shipping about two-three bucks?

These are the u-bolts that holt the control arm shaft to the cross member? correct?

At some point GM went to a larger U-bolt (from 7/16" or 1/2" to 9/16") You just have drill out the holes to fit the new bolt. Probably why the part# isn't correct for our year.

I just put the stock u-bolts back on my '67, they definitely
look smaller than those in the picture.

LMC has them listed for 12.95 ea.

I'm definitely going to get some of the 9/16" u-bolts. The stock ones weren't in the greatest shape anyways and no one needs a lower a-arm flying off.
