I was expecting to have made more progress at this point, but ... life.

Yeah, but, IMHO it is much better to take your time than rush and make mistakes.

Time to make the bushings for the front of the final drive. Bit of a weird configuration, so I made the bushing as two pieces, a complex shape that presses into the front ears of the diff, and a disc to serve as the lower isolator. The Ronin guys sent me a link to a guy that makes something like this, but I thought the version I came up with was a little better designed and didn't rely solely on the press-fit to hold the diff in.



Sorry the pics are so dark.



With the front cradle mocked up. Everything fits surprisingly well. The Ronin guys did a really nice job with the front piece. I think just a little minor grinding will be necessary to tighten up the gaps for a nice weld. I have a bit more work to do before this is ready to weld but it's mostly just prep.



This is a shot of the rear bushings I made, fitted to the Ronin plate, bolted to the RX-8 subframe.



This is the front mount, with the bottom isolator bushing installed. You can see the gap from the Ronin front plate to the subframe is just a bit on the large side, probably okay for a MIG weld but a bit too large for a TIG.

Continuing work on the 8.8 swap. Final test fit before grinding everything clean and welding.



Good fitment to the front of the subframe, TIG welding this was not a problem at all.



We also put a bead on the underside, where the rear of the front plate meets the RX-8 subframe.



Cleaned, primed, and rattle-canned black.



Here's a close-up of the lower "legs" of the front plate welded to the subframe.



Another close-up of the welding on the front plate / subframe interface, as well as the front bushings, with the final drive installed. There were no fitment issues after welding.



Top down view with the final drive all bolted up. Looks like it was meant to go there! The Ronin kit is awesome...
