First I've ever heard of a thickened steering wheel causing any issues down the line - and I've had heaps of them done. I always use Royal Steering Wheels - admittedly never had any issues like John did. Postage to them is cheap - use parcel motel and its 8.50 or so insured, and you can have it sent back to your parcel motel address to keep the cost down.

I've contacted the Pieter lad on donedeal several times, and he's the flakiest operator I've ever dealt with, well maybe not - given some of the plonkers I've had to deal with. Maybe he's bitten off more than he can chew, but he just stopped responding to messages on the two occasions I tried to get him to do some retrimming.
