Finally time to put the side skirts back on, once get the rattle can paint I ordered to paint the torsion bar covers.

Another topic: Anyone going to Hershey?

Congratulations glad you got it sorted, Matt really knows his stuff with the old cars.

A few of us are headed to Hershey

Well, it's been a minute, so thought I'd provide an update and ask for some advice.

Been enjoying the car more and more as the years have gone by, now 185K on the clock. I did a top end last winter, taking my 3.0L to a 3.2SS (964 cams, 3.2L piston swap with 10:1 compression, lightened flywheel and some other less consequential changes). Still running CIS! And even took the car on the track in Sept '22 (Summit Point; not eager to return, I will stick to road rallies), though I still have yet to do an autocross.

Things took a turn for the worse at the end of this Fall - had a violent pop out of first gear, and a sinking feeling in my stomach. I dropped the gear oil and found a number of dog teeth caught by the magnetic drain plug. I'll have the engine and trans out of the car in the next week or so.

Not excited at all to spend the $$ for a gearbox rebuild (though in all honesty a re-seal was due) so looking for suggestions on how to do it on a budget. I'm also a "do it once, do it right" guy, and I find myself looking longingly at a Wavetrac LSD, billet side cover and retaining plate. I am certain that I am not the first person on this board to be in the same position.

Would love to hear the experience you have with rebuilder or advice on DIY solutions. What would you do? What would you not do? I have no plans to sell, just want many more years of enjoyment.

Thanks to the group!

Michael,
I went with an OS Giken LSD on my 915 transmission (about 11 years ago) and it was great. Not sure what the comparison is with the Wavetrac, but I know we had no problem installing the OS Giken (by "we" I mean the Dorki who helped me while I watched).

If you decide not to do it yourself, it would certainly be less expensive with the transmission already removed from the car. The mechanics/shops I've had excellent experience with for these were Matt De Maria (Stuttgart Performance Engineering - now in the Montgomery Air Park), Billy Ring (Performance Auto Works, out kind-of near Summit Point--but talk to me about Billy first if you're planning to take it there) and Charlie Murphy (Intersport/Tysons shop).

But of course doing the rebuild working together with the right Dorki would be more rewarding (and less expensive) in the long run.

Yep, spoke with Billy - he refurbed my heads and cam boxes when I did my top end, very satisfied with the results. He's SUPER busy, I got the impression that probably couldn't get to any work given to him today for 6+ months.

Will reach out to Matt! Thanks for your reply.
