You could lose some of the mass in the rear end mounting plates. Anything outside of a line drawn from a point 1.5 bolt diameters out from the top and bottom bolts to just to the rear of the axle centerline is really just ballast as that is all that the rule requires. I use the Strange H1110 housing in most of my builds and I normally make the bracket come vertically up (and down) off the housing for about 1/2" and then radius it before running it straight to the top and bottom mounting points. That said, if the brackets are landing on a floater spindle or out on the tubes on a normal housing I normally make the bracket so that I can bore the hole for the tube and slide it over the tube before welding the housing ends/spindles in place. Again I usually only leave about 1/2" of material outboard of the axle housing end.

Well I have the coupler cut and fit in. I was able to trim it to size and have enough space. slides in back and forth with ease.
Next up.
Larger trans and raised so now the steering cross member hits the trans. lol.
Will move the cross member back a little bit, raise it up slightly and make a new bracket for the box.

OK!. Update--------------
Have been working hard on the frame. redid the upper rails and put new uprights in the middle. added diagonals in between them. slid a PROPER sleeve in the upper rail and cut new pieces of tube to fit in between.
No way I was going to get the inner sleeve to slide in so I used a really thin zip disc from work to cut both new tubes in half. clamped them on and made a 1/16 gap all around for welding. there's 4 holes on each side for rosette welds. just waiting for my welder to get back in town.
Picture 2 is moving the cross member up and back as raising the motor and trans, the cross member hit it. cut a bracket for the steering box and weld on the tabs.
then pull it all apart when the welder get here lol.

Another one lol.
Had a friends son come and do the welding for me. He did a nice job. boilermaker by trade. has lots of coil tubing and stainless experience. Now all I need to do is all of the little brackets to install everything. about 3 weeks from now, will get it blasted and a nice coat of epoxy. Just in case I need to add something. A lot straighter than before.

Update!
I've been working on the rail quite a bit. Blasted the powder coat off.(PITA!) and painted it with epoxy black. Just in case I needed to add or change anything. finished cleaning and lubing the front end. nice and smooth now with no binding. put the engine, trans and rear end in. all straight and even. now time to finish all the little stuff. 38 days to go until I get my licence. here is a couple pics. front, side wiring and gauges and coil.
Barry.
