Maybe it's a dedicated track/drag, car why would anyone want nos on the street?? I would personally go the 32 over vr coz it's still a commo at the end of the day
I bought one from eBay few years ago for my old 33 can't remember cost but was cheap I fit it myself no worries I think there was minimal mod I had to do if any to fit
Hope that helps mate
Why don't you take the one off that your going to replace, take it to the shop with you compare. You are guaranteed to get the right one then
That's what I do anyways
Ohk not familiar with RTA but I would just put down the original km's as they are the "original" km's of the car and just explain the new cluster if need be
Hope this helps
