[Healeys] Off the Gauge

[John Rowe]

Hi  Alan

What an extremely good solution to stop that OD leak.

I have Tarmac Rallied my car for the last 12 years and the gearbox 
restraining mount works perfectly with standard rubbers but I do have a 
leak at the OD flange.

Hopefully :-) that leak in now in the past as both the car and I have 
retired.

cheers from West OZ
