Most junkyards here want 300 bucks for "any gearbox" like a t-case or diff for older vehicles,so 50 bucks isn't that much for a rebuildable core,since the ones at junkyards often sit outside forever before being sold,and usually suffer some water intrusion...................................................................its getting harder to find any older T-cases now here...(one you can toss right in and use anyway)...If your looking for a NP-205 for a TH350,I have one with the adapter for the t-case and shifter I'd sell....It was in my 77 GMC,I got it from a '72 K20....worked good in 4-hi,I never used 4-lo because the shifter hit the floorpan and wouldn't let it engauge all the way,and it would pop out...I saved it when I parted the truck out and scrapped it...PM me if your interested,I dont want to get in trouble posting something for sale in the garage....
