Cheers Mat, thanks heaps again mate, truly appreciate your help with this. I found the link again that scared me initially to post before. https://www.valvesonline.com.au/references/threads/ It was the 55 versus 60 degree angle that spooked me. Picked up the yanky oil thermo from Burson's legends on the way home from work tonight. Really does seem well made, just was worried about the cast aluminium threads being buggered up from my mechanical butchering hands:-)
