Rear disc conversion, is it worth it?

[swamp rat]

You have a 14 bolt so parts are readally avalable, my take is the drums are adaquate.

I did the conversion on my Ho52 as parts are becoming hard to come by, I have no regrets but i have not been on super wet conditions to see if its better or worse, I also replaced the proportioning/distribution valve with one designed for 4 wheel disk applications. I would think that being as the front disks provide more stopping power that the rears should be fine. There is another opinion that the reduced surface area of the disk VS Drums will aid in heat build up on long down hill slopes but i think the disks cool better.

Only draw back using a chevy caliper is no E-brake and the law books say ya gotta have one (maybe not every state??) You can ise Eldorado calipers with mechanical E-Brakes.
