Are the upper and lower a-arm bolts supposed to be:
course or fine?
lock washer or nylon nut?
washers or no?
length?

I removed the lowers and had two fine, two course, 1 grade 5, 1 grade 8, 2 10.9's...in three different lengths...with 5 washers...

I'm going to the fastener store tomorrow and thought I add these two the list.

Thanks

Scott, Get the correct flange head bolts and nuts at one of the aftermarket warehouses. Those are specialty bolts with lock nuts so they won't back off. Also, a regular grade 8 bolt might fatigue under stress.

Thanks Dave. I'll look at the aftermarket sources.

Check out AMK Products at http://www.amkproducts.com

I recently purchased complete front end and engine kits from them and I have to say, the quality of the fasteners was brilliant. As well as the kits, they also sell most items individually.
