Thought I'd close this out:
1. I can confirm that with the minimum of a special home made tool (8mm Allen Key customized to lock the Pulley and 17mm offset ring spanner!), you can remove the crank Pulley quite easily without lowering the engine or removing the muffler.
2. I purchased a genuine Porsche crank pulley (# 91110201704 V-BELT PULLEY) and a new flange'd hex bolt (# 99909300502 HEX BOLT).
3. when I checked the new pulley by the same method it was so much better than the original less than 0.3mm wobble (Was at the limit of my measuring set-up).
4. When I installed the new Pulley on the crank with the new Hex bolt and run the engine I could not see/detect any wobble at all it was perfect/true (Unlike the original).
Still a mystery how the original got distorted in the first place. There was a suggestion that the pulley's have been known to distort overtime/45 years. !
Thanks again for the support.
