Believe it or not, I've actually been working on this thing again!
A few months ago I bent up some simple "framerails" that have been sitting on the floor in my way. I finally made some temporary crossmembers to hold them together and got the body set in place over them. (mostly hanging from the ceiling in position, since the frame is nowhere near strong enough to support any real weight yet) I bent some rocker protection pieces to match the not-quite-straight body, and began the body mounting--which is the cage sandwich plates, I'm not going to bother with standard body mounts. Nothing will rely on the body for any structure, everything will be tubular structure with some sheetmetal sandwiched between here and there.
Keep in mind I still need to add the 2 1/2" filler piece to the front of the wheelwell, so that will mostly hide that tube. I'll cut and cap the nerf bar at that time, to match the line of the wheelwell.
I swung the engine/transmission into position, cut the necessary hole in the firewall for the intake to pass through, then bolted on the newly-rebuilt D300. (remember the engine was originally a front-wheel-drive application, so the intake is on what is now the back of the engine) The D300 has a Teraflex HD rear output shaft and 4:1 gear set. The 300 doesn't hang down too far below the initial frame, which is nice--since I'll make the belly pan part to fit how far it dangles. I could tuck it up through the floor more, but the top of the engine is already close to the hood, and if I angle the Tcase up it'll hurt my rear driveline more than it'll already be hurting.
I also custom-fit a Ford Taurus fan to the radiator, a little grinding on the left side around the ports, and shortened the right side by about 2 1/2". I just cut the shroud, and put the original end back on by plastic-welding it with my soldering iron. I also have a nice blister on my hand where I slipped and burned myself pretty good. :-\ It's hard to make the plastic look at all good, but it's solid. I need to find some aluminum bolts or all-thread to have welded on the tank to mount the fan, hopefully they exist. I'll also have to have a "dam" in the middle of the left tank so I can have both the inlet and outlet on the same side.
Next up, front end stuff--shock hoops and motor mounts, stuff like that.
