Lots of info on this in the FAQ section but I would definitely recommend a disc swap. I have used the JT kit long ago but there are better options IMO.
I believe I saw your van last weekend as I was traveling south from Blue Ridge through Atlanta. Maybe on 575? If not there’s one just like it Atlanta. Cool vehicle. GLWS.
Found both. Thanks for input. Found wheels from a member and the chrome bumper from Specter Off Road. Shout out to them for sourcing a rare brake master cylinder for the BJ44 (JDM) with front disc and rear drum.
