1970 K10 Disk brake options - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I want to put disk brakes on a 70 K10. I have a 1979 donor truck. I can go measure tomorrow, but does anyone know, offhand, if this is a bolt in swap?

Thanks,
Larry

I think it is a bolt in deal. See what others say for sure.

direct bolt in, you need a new master cylinder and prop valve. you can get adapters to hook up the brake hoses

Just make sure that the gear ratios match. The '79 is likely going to be a 10 bolt with the 28 spline inners. Not too bad if it is just a daily driver.
