42RH / A-500 in a Duster with pictures.

Ignoring what I have to do in the guts of the transmission here is a list of stuff to be completed to install the transmission. Shifting OD and lockup will be detailed later.

1) Find a fairly flat mount to use as a transmission mount that is close to the 42RH bolt pattern. One board member states Energy Suspension 3-1108G works which is a GM application, 1964-2001!

2) Reenforce the area that has been cut out without hitting the transmission.

3) Fabricated a new crossmember (with four holes) for the trans mount.

4) Get the drive shaft modified. (local shop)

5) Longer speedo cable from another application like a C-body or truck perhaps.

All the other stuff like the linkage is a bolt up so should be a non-issue and I already have the magnum flex plate.
