OK...so I've been digging for brake info...and there is enough to make your head spin...and yet there are huge gaps in info...so this is what I have, and correct me where I'm wrong. My goal is to determine what I need to upgrademy front brakes being as I have the 4 cylinder brakes.

1- I see lots of references to V6 brakes..what I've noticed I'm my research is this: in 88 the calipers changed and are the same for all remaining years of Gen 1 regardless of engine OR wheelbase.
2- Caliper brackets however are different between 4cyl and V6, and the reason is to accommodate slightly beefier rotors on V6.
Question: is the mount point for the bracket on the steering knuckle/spindle still the same between both engine variations? IE are the brackets mountable interchangeably?
3- V6 models use a larger booster and master cylinder than 4cyl
Question: will the V6 booster bolt in a 4cyl with modification?
4- I cannot find a listing for 87 and under pre-V6 caliper brackets, the calipers are different, and the rotors are different (part number-wise anyhow)
Question: do any of the later model Gen parts swap over to the early models (87 and older)?
Question 2- Has ANYBODY swapped Gen two brakes to an early Gen 1?

Edit: dug through FSM and discover than early (87 and prior) Gen 1 doesn't have a caliper bracket. The caliper bolts directly to the steering knuckle/spindle...
Question: can later model Gen 1 spindles be swapped into early models?
