rear disk brake conversions

[cruzito1]

I have a 63 chevy stepside longbed

it has a 350 engine and trans from a camaro

and a disk brakes from a 88 chevy 1500

I still have six bolts on the back and the new 5 by 5 bolt pattern in the front

Im trying to match the bolt pattern for the back

So I was thinking of changing the rear end to disk brakes

I don't have a lot of money because my wife is close to divorcing me cause of the truck and the time I spend on it

I use craigslist to find deals on parts

sometimes they fit and sometimes they dont

so my back yard has a lot of extra stuff that didn't fit

My question is...

What is the most inexpensive way to get my rear end to have the same bolt pattern as the front?

Do I have to change the whole rear end?

Or is there a way of just changing the axles that go to the drums

or should I just buy a rear end that has disk brakes on it?

I guess I could just look for six lug disk brakes too?

The thing is that I was amazed on how easy the spindles and rotors fit into where the drums where. I was kinda hoping that It would be just as easy to switch out the rear drums for disks too.

I heard that 72 to 87 spindles fit right in and even though they came from an 88 chevy 1500 it still worked.

I hope someone out there knows what Im trying to say or ask....

Theres some dropped spindles for a 92-98 1/2 ton truck, would they fit my 63?

respectfully,

Carlos
