73 dart

The 73 should have spool mount motor mounts. The 71 will have
the biskit mount. Just go to the parts store and get the upper
spool mounts to put the engine in. The 73 has the lbp wheels.
You can get alot more wheels to fit this set up. I would stick
with the big bolt pattern. Probly has discs on the 73, and drums
on the 71 anyway. I would like to tell you it should be a bolt
in project. Good luck. Brian.
