So I bought Chuck from Pigeaten and I am looking to take the 4 wheel disc brake conversion from the 05/72 that is on mine currently and move it over to the 05/70. But I noticed that the brake booster is not located in the same place. On the 70 it is about 3 inches closer towards the middle and will not allow for the booster to fit. Do I need a booster or can I just upgrade the brake master cylinder? This is the JT Outfitters kit that was on the 72 when I purchased it.
