dipstick and tube

The issue would be that the hole location for the tube
in the block is in the front and the dipstick wouldn’t
be in the sump on the rear sump pan.

Nope/ not all the way up front, it's shown in one of the pix. Could that hole location be a "model year" deal since I know that pre 72 trucks had a front sump/. In case it comes up, mine is an 85 D150.
