Swapping drum brakes to disc brakes on a 70 D22 Winnie

[Vanessa]

Hey-
I found some great information here about the process of swapping the original front drum brakes for disc brakes, but one question wasn't answered that the guy who is doing the work wants to know: It's a Dodge m300 chassis, and he found a m600 that he thinks will work to swap out. Has anyone had experience with this? Any suggestions or comments are welcome.
Thanks!

Your current setup: M300 (Early) 1969-71
The P200 chassis parts at the bottom of that page can be used for that chassis also.

Dodge M300 disc setup only used a single piston caliper:
RM300 1973-74
M300 1974-78 (Master-Vac)

Dodge M600 used a dual piston caliper on a hydroboost brake system
M600 1976 and Later

You need to find a M300 donor chassis.

Thanks a million, Dave! I'll pass that along. Hope he can get me on the road soon!
