:-\ ??? I've had my cruiser for awhile now (6 years). It is a stock 70 FJ-40. I have questions concerning: 1.) Disc brake conversion and 2.) upgrading to 4-speed tranny. Here goes: 1.)To go to 4-wheel disc do I need a new master cylinder/booster? I have a dual MC (front and rear). I already have the mini parts to do the front and am currently in the process of aquiring the parts for the rear. The MC and the proportioning valve are my dilema at this moment. I've read and read but no clear anwsers. 2.)I am buying a 4-speed transmission (used - will have rebuilt). Can i mate it to my 3-speed transfercase? Do i need a 4-speed transfer case? I know I need to do more reading but any help would be really, really appreciated. On a side note my cruiser is a daily driver and I plan to do some mild off-road. Thanks in advance for your help.
