John Deere 544 Loader Turbo Question

I'm looking for some help on the turbo for my machine. The information on the tag is Model T04B 32 ; Garrett p/n
409940-9007R ; Cust p/n AT 29738. My loader is a 1972. I think this turbo is used on quite a few different applications and if I can find some it might be a help as I live in Nova Scotia Canada
Thank you
Al
