"Drum to Disc" conversions 67-70 pics and videos

just want to start off by thanking Keith for putting together one hell of an amazing and detailed write up on this topic, I would just like to augment it from the end users perspective, following Keith's advice I will be converting what I think is a '69 six lug to a six lug disc setup, I would like to add some pics and videos

[my truck is registered as a 1971 GMC that's why I am not sure of the frame's origin]


DRUM TO DISC CONVERSIONS 67-70

67-70 truck with

67-70 Crossmember Installed:
1) There are many advantage to leaving your 67-70 crossmember in place to add disc brakes.

2) 67-70 truck owners can now purchase "year specific" standard and drop spindles, from many aftermarket suspension vendors.
* No need to change ball joints.
* No need to change tie rod ends.
* These new "conversion disc brake spindles" are a true "bolt-on" mod to add disc brakes to your truck.

3) The 67-70 a-arms can also be used with any other (71-72 or 73-87) spindle, with a simple ball joint change.
* The upper and lower ball joints and outer tie rods must match the correct year of spindle you choose.

4) You will need a "conversion" rubber brake hose to connect your disc brake caliper to your existing steel brake line.
* 71-72 rubber brake hoses can be adapted.
* Much longer 73-87 brake hoses can also be adapted.
* Aftermarket steel braided brake hoses are an option.

5) Keeping your original 67-70 crossmember allows to to leave the engine and transmission in place.
* No need to remove drivetrain.
* No need to temporarily support the engine, while removing the crossmember.
* Complete disassembly of the front suspension also allows you the ability to clean, inspect, replace or rebuild all the individual components.

67-70 Truck With 6-lug Disc Brakes:

6-Lug Drum to 6-Lug Disc Conversions:
1) This 6-lug disc brake swap will include all of the above 5-lug information.

2) The only difference is the use of an aftermarket 6-lug rotor.
* These rotors are new castings.
* These rotors have been drilled with the correct 6x5.5" 6-lug pattern.
* These rotors have the correct 7/16" lug studs that match the original drum brake lug studs.

3) Several aftermarket suspension vendors sell these rotors,... such as:
* ECE (Early Classic Enterprises).
* POL (Performance OnLine).
* CPP (Classic Performance Products).

4) All 63-70 "conversion" stock height and drop spindles will work with these 6-lug rotors.

5) All 71-72 stock oem and drop spindles will work with these 6-lug rotors.

6) If using a 73-87 spindle,... it must be the HD spindle, that works with the 1-1/4" wide rotors.
* The 81-87 LD spindles will not work with these 6-lug rotors.
