wired and plumbed on the K member this morning and strapped to the RAM to run out to Johns and pull VATS from the computer this afternoon.  fingers crossed its happy with no Fuel pressure control module connected and a corvette 58psi filter reg.

runs and stalls as it should with VATS enabled and good OBD communication right now.

If the case cracked with an open diff, how well will it do "locked"?

Cool!  I love the concept of symmetrical suspension setup/links.

That looks awful.

took me 4 hours including welding the diff and letting it cool for a half hour

wasn't too bad, transmissions are fun.  i would feel fully confident in rebuilding one now. 


only fail was snapping a starter motor termanal (after heat and PB) and having to torch out speed sensor (rusted brittle seized plastic).

just found this guys old build thread, using same exact transaxle.

pirate adds are painful but he goes into detail about fighting transaxle c clips.  he even cut a window into the side of the transmission housing lol.


I was going to ignore this and say it would be fine, but i guess not now.  going back to thinking about 4bolt bearing retaining flange and something to hang a rotors before a driveline flange to delete corner brakes also.

realized i have lots of ford 8.8 pinions, flanges, yokes, and 1350 super duty shafts.  should be able to size a 4 bolt bearing flange and adapt to transaxle cup to retain, and support, 1350 drive shaft CVs will be nice also. 


think i have ditched the pinion brake idea... dont these things usually get water/steel shot in the tires anyway lol, i guess that weight will help on the corners


stared at a TC pump today, decided not worth 150$ in my time to not order the CBR bracket on ebay that bolts on.
