77 k10 NP203 to NP205??

[TheBlueBomber]

Hey yall, new guy here from Wake Co. North Cackalacki!!!! Anywho I used to own a 79 K5 blazer that was a rust bucket so after years of tinkering I got sick of it and sold it... Low and behold half a year later (today) I bought a 77 K10 (at parts truck cost) as a play truck so I can go offroading and do all my outdoor man needs... The truck needs A LOT of work luckily the stock 350 runs like a forgotton champion but I have to replace the 700r4 transmission and front axle...


My question is while I am replacing the 700r4 with a TH350, should I might as well change the NP203 Tcase with a NP205? I've been thinking on this route and am ready to jump on it but just wanted to hear what yall think. Should I rebuild the axle and add the locking hubs or just replace the whole thing? Curious to hear what yall think and excited to start on my new build!!! (build thread coming) thanks
