upsrodder:
I'm running a MII under my 53 1/2 ton with a 58 235. When I swapped to the 58 235 I drilled the front motor mount using this template, so that it mounted the same as my original engine (the orginal 216).
The mustang II crossmember welds to the original frame, but leaves the original truck front crossmember (where the front of the engine sits) and the crossmember the rear of the engine sits on so it should be no problem keeping your original drivetrain. When I bought my truck the MII had been done by the previous owner and the drivetrain was all stock, I swapped in the later 58 motor and left the 3 speed and closed rear end, then later swapped in an S10 5 speed and an open rear end.
Here's a Pic of my truck. It's all blown apart right now but when I put it back together I'm planning on cutting half a coil. A buddie that's done several MII setups in the past says that should drop it about another 2 inches which will get it to the rake I'm looking for.
