The tag axle bag on our 87 is "Airide Springs by Firestone" , number on the air bag (rubber) appears to be - AY IT 15L ( what was previously noted as a "S" appears to be a backwards "2") F - near as I can tell. There are not any numbers on the top of the bag plate. There are two numbers under the bottom bag hardware. PN NBD 9661 and on a separate line - IT 15T 3 -
This bag has two studs to secure it on the top plate and one on the bottom centre. A large air hose enters on the edge between the two top studs on the tire side.
Newell is sending me a Goodyear Bag of the same configuration. I will post those numbers when I get it.
I have edited due to errors in reading the numbers prior to extensive cleaning.
--------------------- added info
New GoodYear air bag has been received from Newell and installed. Price from Newell was very reasonable and service was great. UPS delivery to Canada is another story, slow and very high brokerage fees over and above deliver and tax costs.
Newell's description of the bag on the invoice is - BAG AIR R/W 1003589447C STEER
the paper tag attached to the bag reads - 1R11-066
imprinted in the rubber - 566-22-3-021
on the bottom plate - 6 203 and AS3-20-7-055
I'm not sure what all these numbers mean but they must have some significance.
