I think you will be happy IF you gave PTC the correct information, and intended use.
25 -2700 sounds perfect for a mild 360. Don't know the rest of your combo, but sounds like a 3:23 gear would make a healthy streeter.
Have you looked for Semi repair shops, or off road shops in your area??
They may seem unlikely for a car, but if they have a machine shop, they may be able to do it.
There are 2 part numbers, one of them is reverse pattern ONLY
the other is forward, or reverse #70001B
I happen to be looking at shifters now, and will probably go with the Cheetah.
