<div style="direction: ltr;">I received a single rail j type over drive in my spares when I bought the car years ago and I never used. The previous owner used it some but then abandoned it because they could get used to switching back and forth in and out of
OD.</div>
<div style="direction: ltr;"><br>
</div>
<div style="direction: ltr;">My understanding was that these came from the factory with a longer input shaft and therefore needed a shorter drive shaft? My crude measurements appear that the overall length is the same and the input shafts are the same. The
only thing that looks different is the location of the mount to the frame cross member. </div>
<div style="direction: ltr;"><br>
</div>
<div style="direction: ltr;">I don’t remember the P.O. saying anything about drive shafts and I don’t have one in my spares. Could he have changed the input shafts for an easy swap of trans? I think I have a fabricated mount adapter for the cross member.</div>
