ok I'm going crazy with all these parts!! whew!! Anyhow I want to get a M03 and am wondering which is best?

sorry had to do it... actually I've read the little bit on rc-mini and would get the M03M but everyone at the track is getting them so to be different and run a cooper body I think I'll go with the M03. Could somone verify if I've got the parts right to get the M03 to M03M status except for the length.
I think I have plenty of bearings sitting around for the whole car.
50882 TA04 Kingpins
51238 F Parts MWB extension and new suspension for M03M
53345 Toe-In Rear Upright
Is there more and/or are these the right parts? Again I'm not looking to hop it up right now just get the extra goodies from the M03M and then go from there.
Thanks
