So the 904 was in the 1gn trucks and the 2gn has the A500 does anybody know if they can be swapped? at least how the mounts will bolt up? My srt swap im going to do will have either a 727 or a 904 behind it and im trying to figure out how hard or easy it might be to do either one. I know a 904 can be built up pretty decent, and is smaller and lighter and was avaliable so it might be a better option, if it bolts in. If i have to fabricate everything anyways then its pointless and i will just use the 727 i already have since i know it can handle what im going to throw at it
