Only reason i mentioned 1500 rear end swap is its about the same, if not the identical to 1200 in gearing, & taller wheel is only a half inch taller from the ground,virtually no differance.There are more of them around,made them for 13 years,they are less expensive so a mistake would be less of an issue if it happened.
In regards to transmission's gearing.1200 has the best road manners of 1100's - 1500's. 1500's gearing is not spaced like the 1200's, that & rev limiter keeps speed down. If it was like 1200's top, end would be 150+ was dissapointed about this,but torque is (STUMP PULLING) power from idle to 5500 red line.
