I just rebuilt my front end on a 1970 el camino. One of the upper A-arm bolt & washer that holds in the bushing came out. I need to find out the size of the washer and bolt. I guess i missed this bolt when I was lock tighting the rest. Does anybody know what size it is? Please help a brother out.

IS THAT THE CHROME GO FASTER BOLT???

I think it is a 5/16ths fine thread about 3/4 to 1 inch long. I should know this I had three 70 Chevelle Sport Coupes. Mylast one I ha for 18 years. Sold it to buy my Active Thunder! I miss that car

The washer you need to get it from chevy. It is concaved and has teeth on it. On my 70 chevelle I put the polyurathane bushings and on the washers I ground the teeth off to let the front end come up easyer.I put red locktite on the bolt and just snug them . For drag racing.

I'm awake now!!! Bolt is 3/8 - 24 thread - 7/8 inch long

R Addiction, you ever go to Carlisle? If you do stop by and say Hi. Spring Space P-156 Roger

Sauron, I may start looking for a project vehicle, either a 70 Chevelle or a 49-50 GMC pickup. I need to find a garage for it. So........maybe I'll see you in the spring. My brother, IKE, has an old 10 second Impala and he may go. He got me started in all this motor head stuff. Plus he just sold his 41 Apache, from what I hear, so he has some extra money!!!

I have several Chevelles but the newest is a 69 that needs a resto. 2-66's, 2-67's, 65, and a 64 Conv. If you want to talk cell 336 214 6900 Roger
