Had nothing but issues with my TG dual case (started day 1), bought it all new through them and had more down time then drive in the 1.5 yrs I had it. Sold off the new case they sent my to replace the one that I had, went with Atlas...
When shopping for axle housings I contacted FROR and took them a few wks to reply to a question and when I replied and wanted to order I never heard back from them, after read a number of reviews about FROR taken months, months, and months longer then quoted and when there was an issue FROR taken even longer to fix said (no personal exp just what I read but them not even returning my email...), I went with RuffStuff Specialties. I found they offered what I wanted and went that route, had a couple of issues with the housings I ordered, RuffStuff stood behind there product and took care of said very fast, super happy i went with RuffStuff (the housings r top notch).
FYI I have the section of tcase from the chain case laying around with no plans to use.
