1973 Jimmy rear drum to disc conversion suggestions

Hi all,

Sorry if this has been discussed before but i'm new to the board. I have a 1973 Jimmy 2wd and want to do a rear drum to disc conversion. Has anyone had great success with one brand or another or with simple conversions from another vehicle etc? All help is appreciated.

Cheers,Glen

I've seen a couple people use the 91'-96' Impala/caprice rears with great results, and you keep your bolt pattern.

Thanks for the quick reply.
Any idea if the stock master cylinder etc will work with it?

I'm not sure about the master cylinder, one blazer that comes to mind is xxlf250, he has poerterbuilt up front and custom in the rear and i know he used an Impala rear end. Reach out to him, he can probably help you, he also has a build thread for that blazer on here.

Little Shop of Horrors has a disc brake conversion for our trucks.. Do a google search for "little shop of horrors disc brake" and it is the first thing that comes up in the search..

The whole complete kit is $389..

I'm not trying to be a fly in the ointment but why do a rear disc conversion? Stopping power is just fine with with your front discs and drum rears.
My '08 4X4 Chevy Pickup has Disc-Drum....
Just wondering-and I don't mean to offend.

My Blazer is a mall crawler - / Ice cream run / soccer coaching mobile for my family. I just went it as safe as possible which includes stopping as soon as it can when I want to stop. I have always heard that discs are better is all.
