Standard E-maxx/T-maxx Steering fits. The 3905 steering doesn't fit into the recesses machined in and the steering arms don't clear the diff housing. Had to buy older steering for everything to work.

The 3905 center skid plate also doesn't fit... the chassis is machined to accept standard center skid plates.

This is really an extended chassis that will accept the 3905 transmission than a 3905 chassis. No big deal because I love the chassis, but if you call it a 3905 chassis, everything should bolt up from a 3905.

Finished the build last night... will post pics if I get a chance tonight.
