The number comes from the GM packaging label on the kit I purchased through the Parts Department. Interestingly, the Installation Instruction Sheet shows the part number as 19179360.

NOTE: Not included in the kit is item #15 - GM part number 25744730 - wheel stow strap. You have to order it separately. Also, I couldn't identify item #11 - maybe someone more knowledgeable can provide it's identity.

#11 is a sound deadener. we sell the kit for $215.00 plus shipping if anyone needs one.

Do you have a GM part number for the sound deadener?

Do you have a GM part number for the sound deadener?

That is not serviced by GM. I suppose you could just use some generic sound insulation material cut to fit if you had to replace it.

Does it matter what size wheels one might have, 17" or 18"? One size spare fits all? Just curious.
