    Default What Size Rear Do I Have

    What size rear, what Trans do I have. I would like to order on line like GM Part Direct. I gave them my Vin # they say rear cover gasket has 14 Holes, I count 10 Holes.
    I would like to order Trans Filter, Pan Gasket, rear end cover gasket.

    Did you buy your truck new or pre-owned? If new, do you still have the window sticker? See if it says on there what rear end you have.

    Your Welcome Dave...........also Inside your Glove Box is a White Tag/Sticker....which is the Service Parts I.D. Tag(Pictured Below)and on it you will see your Vehicles Vin # Number and a Series of Letter's and Number's which are RPO Codes.....which stands for Regular Production Options...In Short its what your Vehicle came with from the Factory,

    the Service Parts Identification Label
