Shouldn't need anything since a th350 is in it.

crossmember and drive shaft are the same?

I'd think they are but, better off measuring the length of the transmissions. Some come short and some are long.

As for the crossmember you can check BMR suspension and just look at the conversion crossmembers. I think they are the same too

You'll need a new drive shaft yoke (they are not the same), cross member, tranny mount, and a kickdown wiring harness since the kickdown is electronic instead of cable-actuated. That's about it I think.

You will need:

Crossmember, as they are different.

Driveshaft, may be a different length, I haven't done this swap so I'm not 100% on that

If you have a rmvb, you may need a different shifter.. if it's a std valvebody, you're good.

There is no "kickdown" crap needed at all if it's got a manual valve body.. which I couldn't imagine it not to have a manual one.

the th350 in it now has rmvb already so the shifter should work

Correct, if the th400 has the same type of valve body, then it's just the crossmember, and driveshaft that should be needed.

Yes cross-member is correct, how are you mounting your torque arm now with the TH350?
