I would just like to throw the idea out there since the 7074rc chassis is 3piece this opens up a lot of options. The chassis could be lengthen or shortened by using different front plates. Or we could use different hole patterns for mcd or losi ect front ends or back,I wouldn't mind the 7075rc diff boxs milled to take mcd LSD diffs/ input shafts. They might fit now with the right bearings. Just a idea, the redcats diffs are pretty tough.
