It's a bit hard to tell from this distance. You'll have to email the guy and ask HIM - he's the only one can tell you. Hope he tells the truth
I have an RS2000 gearbox down in the shed if you are interested. $100 will buy it - it was OK when it came out of the car but I'd recommend that it be reconditioned. Check out what that might cost??? The ratios are the same but it has a quick shifter.
