Anyone know where I can buy this type of 5k pot?

The key things to identify are the shaft diameter and whether it's a linear or logarithmic pot.
Shaft can be done via measurement obviously, for lin/log you need to check the resistance at the fully closed point, half open (in terms of rotating the knob 50% of it's total rotation) and full open. It's probably going to be a linear pot which should show you:
0 Ohms at fully closed,
around 2500 Ohms half open,
5000 Ohms full open.
A log pot will show you a value nowhere near 2500 Ohms in the middle position.
After that you can just pick one up from Maplin, Farnell etc. The three contact bit is standard and I doubt you need a long-life/heavy-duty pot.
What's this off btw?

If it's a steering pot then it's definitely going to be linear otherwise you'd have to code a compensation table into the game which would still give weird steering.
So any 5k pot which has the right shaft diameter will work dude. Am pretty sure a super-tough pot won't be required so you'll be able to get this from Maplin's this aft if you're quick!!!!1111

No...Ridge Racer has a massive pot and yes that's in the manual.
I need this for Rave Racer,
But yeah Andy
you must have been reading my masses of posts everywhere
I know what you meant.
Trouble is the only manual online for Rave Racer is an upgrade kit from a RR1 cab, which means it's no good.
I have a spare RR1 pot and it's twice the size inc the length of the shaft, ooooo eeeerrrrr
These Rave ones are smaller, to me this twin Rave cab I have is the same as a Ridge Racer 2 twin and on ebay.com at the mo for $18 + $5 postage I can buy a Rave Racer manual which says upgrade kit from a Ridge Racer 2 (I'm sure this manual will have the Namco pot part no. I need)
That manual is not on the net at all (That I can see) and don't really want to pay the dollars for that manual, although I supose it would now come in handy??
Ok thanks Tim, I shall measure my shaft
seriously though I'll get some more info....hmmmm do I buy the manual anyway??
Thanks all!

Don't forget that with these types of pots the shafts always come extra-long so you can cut them down to size. I'm pretty certain you'll find it's a standard diameter and then it's just a case of proving log vs lin pot which you can do with an in-situ resistance measurement as outlined above. Given it's behind all those reducing gears it's not going to get hammered so anything you can find should be good.
Log pots are mostly (only?) used for volume controls.
Ears have logarithmic sensitivity to sound power. Double the sound power only sounds 'a bit' louder, NOT twice as loud. If a linear pot is used for volume, then the sensitivity seems to be all at one end.
For pretty much everything else, and definitely for a steering pot, linear is the thing.
