Sump Bolts for TR6

["Biedermann, Frank (SSABSA)" <frank@ssabsa.sa.gov.au>]

Chaps,
 
Can anyone tell me off the top of their head (or by looking it up in a
workshop manual) what the sump bolts are on a TR6? I have a feeling
they're 1/2" UNF, but I want to be sure before I go out and get a
helicoil kit... I think I've located the cause of the flood of oil from the
front of my sump... :-)
 
Thanks,
