my lcas
Hey everyone, just a couple of stupid questions . I have a 1986 IROC and i took off my lcas when i went and rebuilt my rearend awhile back now i cant remember which way they go, do the bolt heads face out on both sides or do u see the nutside of the bolt when installed? also im dropping the car another 1.5" from the stock ROC specs am i going to need to worry about lca relocation brackets or anything like that whats your opinion thanks alot for your time Dan-

if the bolts fit, it doesn't matter which way you install them
if wheelhop increases, then you might want to think about relocation brackets... it's up to you really... it's really only a drag racing problem

I think it may matter which direction the bolts go, but only for installation reasons.
On my convertible I have the crappy stock square tube SFC's under the door sills which give me about 1-2 inches b/t the frontmost bolt hole on the LCA and the SFC. The SFC has a hole in it that I have to back the bolt head through and then push it into the LCA bushing hole. SO, my bolts have to go in head first from outside to inside.
But the geometry of non-conv may be different in that regard.
