part number request-4104 rear air bag

[thomasinnv]

I have a friend that needs 2 rear air bags for his 4104. I googled it and came up with part number 2292372. was hoping someone with a 4104 parts manual could verify this number or give the correct one if thats not it.

Correct that is  the part #in the manual.

Tell your friend that 4104s use two different lengths of air bag bolts. Earlier models (I don't know when they changed, mine is a  '54) have thicker top mounts and also the rear hubs are thicker so also take longer lug bolts.

I found all this out the hard way.

If he has blocking plates installed the longest bolts are just barely long enough and actually too short where the air brake can bracket bolts on.
