Revo ?'s

Alright i got a revo BL conversion, im blowing rear diffs(e-maxx), slipper is not too tight, so i've been driving my tekno RC8 w/1515 1y on 4s for now. Are the e-revo BL diffs a direct swap for the Revo 3.3? The tranny is fine for now thanks to RRP, half steel half plastic for less rotating mass. Doess the E-revo BL tranny drop in the revo 3.3 with little mods? i know the emaxx does but i've got the RCM mount on it that uses the traditional revo tranny. I've toughed up the original 3.3 tranny with plenty of axle pins lmao. Well i guess all i need to know is are the e-revo BL diffs a direct drop in for the revo 3.3?? Thanks all
