This is a New GM 2004R, TH125, and 440-T4 26 tooth Brown speedometer gear and Oring. This will even fit some of the Front wheel drive V8 cars like the Oldsmobile Toronado with the TH325 as well.

Here at American Hot Rod Solutions we have many other gears in our other listings too. If you need help figuring the correct gear please let us know and we will be happy to help you.
