I am installing a 5.9 cummins in my c-20 chevy and need to know what some of you used for the rear transmission mount. I am having trouble mounting it up. I have finished the engine mounts but am looking for ideas for the trans. If you have any pics it would be great.

It is a 5.9 cummins with a Dodge 727 3 speed trans. Just curious what kind of cross member others have used.

As I recall the 727 uses a spool/biscuit type mount in stock configuration. There are available in polyurethane from all the big Mopar suspension vendors like Just Suspension and many others.

Not sure polyurethane is the answer with a 6BT, but not as much vibration there as a 4Bt so maybe okay. I'd stay with the stock Dodge Cummins/727 mount used in 1st Gen CTD Dodges, '89-92.

You can fab up a crossmember/mount pretty easy but that depends on which particular vehicle this is going in. I have no idea what Chevy uses or how their crossmember lines up with the Cummins/727.
