You can look under AX-10 Ridgecrest. RCcrawler forums has thread for this chassis. Topcad has the vertical plates. But can be purchased from Integy, search under Ridgecrest. The lower links are from the the Wraith. The gear box is from the SCX10. The driveline is from the wraith. You can use a 550 motor but the rear part of the can will one of the lower links and reduce rear end articulation. The shocks are from the wraith also. I have this chassis but I migrated most of the parts to a 2nd hand wraith chassis to use as a FPV platform.
Good luck and have fun.
