I recently purchased a used gearbox w/a J-type OD, only to find that the 
chassis mounting did not match. Another pit fall to consider if you 
aren't handy... Driveshaft must be shortened as well.. Having said 
that..70MPH at 2600

RPM is pretty sweet.  I also installed a 3.45:1 ring and pinion..  
dp          We drive too fast in NM  LOL
