Hey Bela, let's take a look under that steering wheel wrap:

Haha! Just about what I expected, packing tape, something else, and a sticky gooey black mess which must be the original foam.
I noticed that the Taito Grand Champion steering wheels look just about the same, so that might be an option provided the mounting holes are the same. Those would be (just barely!

) more plentiful over here.
Here are some interesting "WTF was that person thinking?" things about this machine.
There's an Electrocoin "THIS MACHINE MUST BE EARTHED" sticker on the rear of the machine, so I assume this was imported into the UK by them. The coin door was modified from the one-slot original (evident by the crooked cuts through the Namco "inspection" tag on the back and original holes, and it still has the coin return under the CP which only works with the original setup) to hold the 2-slot 10p Coin Controls mechanisms.
Only one issue.
There's no way this door could have ever opened or closed properly without disassembling the mechs!

Luckily the door is pretty simple, so I will likely recreate it and set it up like the original and leave this one as-is.
Another "WTF?" was the big circular hole in the bottom of the coin box and the bottom of the cabinet with a bit of PVC pipe going to the floor. Since the door was locked, my best guess is that at some point someone owned it and couldn't get to the credit button (didn't know about Free Play either), so they got the coin box out, cut a hole in it, and cut a hole in the floor with a tube as a guide to get the coins they dropped through out on the floor

Otherwise I have no idea why this was done.
I straightened and painted the coin box, coin box bezel and pedal plate today. The paint dried a lot more "white" than intended

But it's certainly 100% better than what was there. I will probably revisit this again at some point.
Working on cleaning up the pedals and shifter. Took the shifter apart so I could scan its bezel artwork (the pedal being cleaned in the foreground)
Also re-glued the lower back panel of the cabinet.
