Thanks, I don't find that same Amazon view, can you post a link? Mine shows out of stock
When I had Summit in the cart yesterday it showed September delivery. At least that's an improvement.
SDPC shows available but when I called they said it wasn't.
Thanks for checking

You can see the notch on the Bell housing below the dowel hole where the starter bolt sits
A drill bit, this hole drilling tool and a round flat combo file made this pretty easy.

It arrived today so I'm back on track.
I notified John that this will be an issue but haven't heard back. His instructions advise against a universal cable. Something to think about if your considering this swap.

A 160-mile round trip last week, with some mixed city driving and some cruising (but no interstate) netted around 26.5.

Has anyone ever looked at putting a modern transmission in an XJS? Having seen all the work that Xjeffs went through with the Quarterbreed conversion, it seems like a lot of effort to put in a tranny designed in the 1980s.
A 6 speed electronically controlled transmission would seem better suited to keep the car in the sweet spot of the torque curve and offer the option of “manu-matic” shifting without the need for a separate clutch.
Is there just not enough of a market for someone to justify doing the engineering work to design a conversion kit?
