Hi I had an issue with my speedometer not ready correctly when I still had a 16v. It was over by about 15mph. I am dropping in a 20v Blacktop right now and I was wondering what speedo cable I would need. Any one have info on what part number I will be needing?

Thanks,

Tim

speedo cable has nothing to do with the engine, if you're using the stock T50, then the speedo cable stays the same...

Means your speedo drive gear(and mating trans output shaft worm gear) don't match up with your cluster. One is sr5 other is GTS.
Or you have a 4.77 rear...

Oh okay. Any info on part numbers I will need?

well that all depends on what you have currently. do you have a GTS gauge cluster? then i can get you the p/n's for the GTE speedo and work gear if you need those. do you have a standard 4.32 diff? i have access to oem parts need be, PM me and we can work out the specifics

said "diff" meant Ring & Pinion aka R&P
heres the parts you need to convert your trans to GTS gearing fro speedo in cluster.
