How about making a plate adapter to use the D 300 behind a t-18 that already has the bull gear for the D20. I guess it would also work for teh T-150 etc, since they came with a D20 factory. Or maybe the tranny pattern is different. I dunno. I think that someone could make a ring type adapter to run the Jeep d300 in place of D20. What do you think guys?
