I have a 43" Kombi that I am looking to convert back to its original length of 34".

I want to keep the belly length shaft in case I return to it, so I have these questions:

What type of double bend offset shaft do I need for this particular putter (0, 1/4, 3/8 or 1/2); and

Has anybody had problems heating the head to remove the shaft, given the aluminum body? I will be using a heat gun, not blow torch.

Thanks!
