Okay, I decided to go with the Herms plate and a manual reverse rotation box. I decided that this would be the way to go, as I would need to redo the mounting on my PTO winch to fit a Saginaw, and I like the idea of the box not being out front. I'm trying to get all the fitting & mods lined out before I remove the body & overhaul the frame, that way all the drilling, welding, etc. will be done. I got a box today, mounted it to the plate & slid it in place. I put on the rear dump manifold off of a 77 Skylark. The manifold is in the way of the steering shaft - as most of you probably already know. I can add a third U-Joint, with the bearing at the intersection of the frame rail and motor mount tower & it will work fine. Of course, the PTO driveshaft is in the way. I can move it over towards the oil pan a bit, and up, to clear the rotating pitman arm. When I move it up, the shaft hits the "radiator" crossmember. To correct that, I need to lower the winch about 3/4", which looks pretty easy & will not require chopping up the mount. It's amazing how one thing leads to another. Sorry for no pictures, I'm still working on that, but spent the da in the shop, instead of on the computer. Looking at pictures, it looks like a box from a '67 or so Mustang would fit nice. The input shaft and housing would be up on top of the frame rail instead of inboard, which would make the steering shaft line up without the exhaust manifold interfering. It looks like a reverse rotation box. I'm assuming that it won't work for some reason that I haven't thought of yet, or someone would have done it, but I can't find any info anywhere where it was tried. Any thoughts on this ? What am I missing ?
