Hi Tom,
Like most Locosts, the driveshaft will be quite short (22", I think). The front yoke is off a front axle of a 4x4 truck and quite narrow by design for packaging reasons, but will easily handle my 300 HP Phase II engine. The drive shaft will go in from the rear. I'll have a removable panel in the boot section for taking it in and out, if necessary, in maintenance scenarios. Most likely, I will just tie it up to the top of the tunnel structure when removing the engine/transmission, which go in and out as a unit.
It's not a good photo, but you can see the front half of the yoke in place in the photo below. The top of the tunnel will be removable for access. However, I'm considering having an access hatch in the undertray below it too. I'll make that decision when I set up the floor to be welded in place.

To make more seat room, I wanted the narrowest tunnel I could get. And, I got it too. You can see the yoke fits through, but without much space to spare.

Three of the lower seat belt mounts (outboard on pass & driver's) plus the driver's side inboard are pretty much the standard Haynes Roadster tabs welded to the chassis rails and tunnel structure. They are 1/8" plate, welded both sides, having flange nuts welded in for blind attachment of the bolts & washers (no nut required). The passenger side, inboard mount is embedded in the large, 1/8" plate that ties the tunnel structure together on that side. I had to cut away a vertical tube to make sure there was enough room for the drive shaft to have adequate clearance.
If you want more detail just let me know and I'll dig up better photos of them.
Nice to hear from you.
