<div>I only cut the left side factory mount off as it directly hit the
($200+) solenoid and used the factory angled rubber bush cross
mount on angle and square iron bits. So, the rubber bits can be
replaced, but the cross piece has to be partially removed to
remove the drive shaft. A small inconvenience for the next luck
owner.. A types were 22% or 28%.. I'm thinking the J is 25% ?
With the newly added 3.45:1 rear gear set 70MPH is showing
2600RPM. Nice for our NM long distances.... Factory is saying 90wt
gear oil... what is your recommendation for oil? Seems heavy for
cold weather temps. DP<br clear="none">

the A to the J-type and modified the frame to
