help with M936A1 wrecker

[saratoga]

mechanic requested 2 rear brake chambers and 1 wedge for M936A1.

Im finding the NSN 2530-01-125-6076 in the TM Ive been using (9-2320-272-24P-1)?

Some of units offered dont list NSN and just say M939 Series 5 Ton Brake.

think i already purchased an incorrect unit (nsn 2530-01-126-7869) and truck is really far away, 6k miles

head is spinning looking at all the parts, can anyone give some guidance? thanks

Wedge assembly replacement is E-1261 in Euclid.
Spring brake pancake diaphragms are DP16s.
The Service brake pancake diaphragm below is a DP12.
The whole spring brake piggyback unit is Meritor # A3280-E6817. Cheapest on Ebay.
The wedge/adjuster rebuild kit is NSN 2530-01-391-32. 28 found on ebay pretty cheap at the moment.

thanks for the info
I think i was just confused with a listing on ebay as it was half priced compared to other assemblys

seller had nsn [FONT=&quot]2530011256076 [/FONT]listed, it was on the box label on all surplus stuff, but titled it as LMTV/FMTV Brake Chamber. Other sellers had same nsn but for M939 family of vehicles.
