brake conversion

[corbins]

Ok, this is NOT Shelby specific, trying to give my son some guidance.

he bought a 67 coupe that a PO had done a disc brake conversion on. There is/was no proportioning valve in the system. I suggested just using a complete 68 set-up (distribution block/proportioning valve ) and appropriate lines.
Anyone see a reason not to go this route? I do know it currently has a single pin switch vs the 2 pin 68 switch.

Thanks for any suggestions !

You can do that. It would be best if no lines or distribution block were yet installed if you do. besides the brake light issue if you change , If you already have all of the 67 lines and distribution block installed it may be more efficient to plumb the proportioning valve (same design tube unit as 68 ) in the rear as normal 67.  No reason to reinvent the wheel and expend unnecessary labor if you don't have to. You are not going to see much of a benefit one over the other so I would suggest to do the one that requires the least work/money on a driver type base car that will not have a higher valve if original or not. Just my thoughts since you asked.

Thanks Bob, he had already removed for replacement all the brake lines. But when he purchased the brake line kit , the fittings at the distribution block were the wrong sizes. They we discovered there were 3 different line sets applicable to the 67s. And as it had no existing proportioning valve, I figured it would be just as easy to change it all over to the 68 stuff, with the exception of the 1 pin vs 2 pins switch, which I'm hoping we can just change out.
