Thanks Guys,
This advice was from the Oz Morgan agent here in Melbourne. He (apparently) sourced the info from Morgan UK! For technology decades old it completely threw me. Moreover, I thought the wire wheel would be flush with the drum for added security and remove reliance on what are quite short small screw bolts! I have emailed Morgan but will now contact Brands Hatch Morgan as recommended. Forking out GBP 2000 for parts alone did not go down well with my "manager"!
