MG MGA - Speedometer Cable Tap Size

In installing the new cable for the speedometer I screwed up the threads on the cap fitting at the gearbox end of the cable. @#$%^&. I can pull the cable out of the way to rechase the threads. Does anybody know what size tap I need to get. The new attachment caps are aluminum. Be careful - very soft steel.

Cheers,

Larry,

I have a thread gauge that might fit in there. I will try to find it and go check for you tomorrow.

If I can't figure out what your talking about, I'll call you. Are you off for the day?

I think you mean the fitting on the engine sort of near and just aft of the header pipe to exhaust junction - right?

Hi Jim,

The speedometer cable has 2 ends - one for the gauge and the other that attaches to the transmission. I've messed up the threads on the fitting that connects to the transmission. Hope that helps.
