Thank you for the replies gents.
The spring is a bit of a beast so I’m wondering if a clock spring might struggle with the workload but I will look in to it.
I’m also going to contact Irwin in the morning with tightly crossed fingers. You’ll no doubt be aware that they don’t make ‘em like they used to so I’m hoping that they still carry the old parts, as some are showing as discontinued.
Best wishes and I’ll let you know….
