Both require an alignment.

No camber kit required (its not a Ford). But make sure you go to a competent alignment shop that can align a classic and knows what alignment shims are.

Spindles require disk brakes if not a 71-72, or already converted.

Spindles may require a wheel change. Original drum brake wheels may interfere and some 15” wheels (depending on offset) may hit the lower control arm.

Spindles give you a guaranteed drop.

Springs give you a questionable amount of drop based on original specs. Example, your original coils have likely sagged 1” from 50 years of use so a 2” spring may only give you 1” drop.

If you decide on spindles, make sure you buy drop spindles for your year. IE don’t buy ‘72 spindles if you have a ‘68 or else you will have to replace ball joints, tie rods, and center link.
