That's great news; thanks! I'll also definitely drop Mike a line
about that tailshaft if I end up getting this combo.

In this case it hopefully won't matter since I can get the engine
and trans out of the same vehicle in one shot, so I already know they
will bolt to each other, it will just be a matter of phyically fitting
them in the van, and there's going to be some fabrication involved
there either way.

That's good to know; thanks! Do you happen to know if the 4wd
transmissions and the 2wd transmissions both have that provision for
the speedometer cable/sensor? I seem to recall that the 4x4 trucks
got their speed signal from the transfer case.
Thanks again, Tom!
