XJ12 5speed conversion

Hi Tony-
The extra two teeth don’t matter. Don’t worry about it.

As you observe, not a problem. The alignment is handled by the dowel pins.

If you are using a hydraulic TO bearing, you MUST get the bellhousing and engine block center to less than .01" TIR (total indicated runout.) I thought mine was close enough, it was not, result was leaky bearing about 3 weeks in. I used readily available offset dowel pins and a better dial indicator setup and got to to .0045 TIR. Maybe you already knew this, but if not, now you do! :slight_smile:
