Are you trying to stay with 6 lug wheels or do you want to change out to 5 lug wheels?

Most people that switch to disc brakes want the 5 lug.........I havent' seen any infor on 6lug discs. Anyway, what's your boxer's name? I have two. A male and a female. Female (Silk) 6 years old and the male (A-K) is almost 4 years old......Luve me some Boxers.

^^Silk

^^AK ......like the gun.

For the "most" part, you have to purchase the required parts brand new, as there's only one option for pulling parts and you will end up with a different bolt pattern than initially available on these trucks.

On my '69 I wanted to retain the original 6-lug setup so I called Early Classic Enterprises (spoke with Mark) and had a complete disc brake upgrade kit and lowering kit on its way. The kit included everything I needed except for brake fluid and bearing grease. Check out my build thread in my signature (Project: Blank Slate) I have a complete write up on installation.

Also, remember this.... when you add disc brakes to a 67-70 truck it will widen the front track width by 1.5" over all (.75" on each side). This explains why the offered a wider rearend from 71-72; to compensate for the disc brakes.

Here's a shot of my truck lowered with a 4.5/6" drop and 6-lug disc brake upgrade:

Cpp now offers a spindle kit that will accually narrow your wheel base....I know a long time coming....they will allow you to buy some parts locally ( I think it will save mostly because the parts are so heavy and shipping kills) but you are going to need the 6 lug disc from them also
