Hey everyone I’m installing new tubular control arms on my 1971 skylark now do I put the old spacers in on the tops for alignment?
The spacer are shims that adjust the caster and camber of the front end. Even if you put the shims back in exactly as they came out, there's an almost 100% chance the alignment is now "out to lunch" as they say. So my best advice is to drive it right to the alignment shop
All cars are by design need a minimum of one shim. If they made the mounting point too far in, you could not adjust them. Hense, the need for shims.
