Just purchased a 1990 Scottsdale C1500

[cmlindauer]

I am new here and looking for some help. Does anyone know how to read the codes in the glove box. I want to know what tranny I have or am supposed to have. I know the VIN codes but not tranny and rear. If anyone knows where I can get this info it would help a lot. I know I have a 350, an overdrive trans and a open rear other than that nothing.
Thanks

Anyone?

Trans codes start with an M, what are yours? I'll look it up. Rear axle codes are G.

Are you asking about the RPO codes?
