I'm researching the V6 front brake upgrade for my buddy's '86 4 cylinder and want to run this past the experts:

The front rotors off a '94 SR 3.5l Montero SR are listed as 27mm thick by 276mm wide. These seem to be the thickest factory type rotors, and very inexpensive, new. Will these fit the stock '86 hubs and clear the knuckles and steering arms? (I know I will need matching '94 SR backing plates/dust shields.)

Front dual piston calipers and mounting brackets from the same '94 SR. Should fit the stock knuckles, right?

The front brake hoses are listed as different lengths with ends that appear to be the same in pictures and thread type, Should I use the '86 upper hoses with the '94 lowers, or all '94 hoses, or will the '86 hoses fit OK?

The booster should be from a V6 Gen 1 with a 15/16" master, correct? Late '88 4 cylinder masters seem to have the larger 15/16" bore, but have the same outlets as the '86 in pictures. The bore depth for the pushrod is about .060" deeper with the 4 cylinder master. Will this physically fit the V6 dual diaphram booster so I can use the same lines, or would it be easier/better to grab the V6 lines? (A new V6 master is alot less $ than the late 4 cylinder type.)

Would it be OK to use the stock '86 4 cylinder 7/8" master, single diaphram booster with the V6 dual piston calipers, or would it lose too much pedal travel and/or require too much pedal pressure?

One last question!

Will the later model (late 88-89 4 cylinders) 15/16" REAR brake wheel cylinders fit the '86 backing plates? (Originally 7/8") I changed to 1/16" larger rear wheel cylinders on my tail heavy Scrambler and it helped a bit, they cost the same as stock replacements.

Thanks!
