8V71 Oil Cooler for M109 Howitzer Power Pack
 

Looking for one of these - oil cooler/ heat exchanger from the 8V71 power pack fitted to the M109 155mm Self-Propelled.

Detroit Diesel p/n 5149054 (another p/n sometimes crossed over to - 5149077 - is just the empty tube center section and won't work out.)

I already have every Google result there is/was, but was hoping someone had one cluttering up the museum workshop or garage or leftover from some project or other they wanted to sell off. Unfortunately the existing one grenaded thanks to water contamination and -35 degree outside storage, so it's a paperweight :(
