Rear disc brake conversion

[dlebo]

Hey so I have a 79 gmc half ton with 5 x 4 3/4 bolt pattern all the way around with a 12 bolt rear end and I was wondering what vehicles would allow for a rear disc swap??

Was your truck converted from the factory 5x5in bolt pattern to a chevy car 5x4 3/4in?

couldn't say for sure that is just what it is. I also think it may be a difference between canadian and american vehicles

Canadian truck had same bolt pattern as American. Are you sure it is 5x4.75? That's car pattern

I'd recheck that...Unless it's been redrilled or subframed (as we found on another member's truck) it will be 5x5.

I had my measurement wrong 'tis 5x5
