Re: lowering 1968 truck and adding disc brakes

anyone? if i do the 73-87 crossmember swap is the wheel mounting surface to wheel mounting surface measurments the same frome side to side on the 67-72 stuff as the 73-87 stuff? and when you do this swap and go to get the alignment done what year model truck do you tell them to use the specs for? 67-72 or 73-87 specs?

booster still works but you need to ditch the distrobution block for a propotioning valve. MC might need changed...

The width should be the same or the difference so minimal that you won't notice it.

Re: lowering 1968 truck and adding disc brakes

I have a 68 in my garage that has hada front crossmember from an 87 Chevy bolted under it and it appears to be very much the same as the original dimensions. I am changing my front to Classic Performance Products tubular A arms and using 3" drop spindles for my lowering.

just be aware that if you end up going with disc brake drop conversion spindles your front wheels wheel have a wider track of about inch and a half on both sides.
