here is my mini starter on a RB/440 with center dump manifolds, truck frame.
should bolt right in, your are looking for a 92-93 5.2 DAKOTA starter.
the stock 68 wires will bolt right to the 2 studs on the mini starter.
FYI...some times there is a plastic extension piece bolted to the 2 studs on the starter for differnt model car/trucks. that will be removed before you install mini starter on the 68 383.
in this pic you can see the 2 studs with a stock wire bolted up, it looks tight on clearance at the studs but the core plug gives it plenty of clearance.
next you might want to check right at the screw for the silnoid on the starter and the block to make sure there is enuff clearance. see it in pic also.
you will notice a big difference in wieght/clearance/cranking speed with a mini starter.
