how to change a full time transfer to a part time?
i recently just bought a 76 gmc 3/4 ton 4x4 now from doing some research i found that they put NP205 transfer cases in it and NP203. I belive i have the 203 but i was doing some reading on it cause i would like to make it part time and i was just gonna go to the truck yard up the road and buy a set of 3/4 ton hub locks and switch the caps on it so it would be part time. And i saw in a forum that some guy was talking about it and said that u need to change some gears in the transfer in order to make it 2wd i was just wondering if this was true of the guy didn't know what he was talking about but if it is how hard is it to change the gears out? and how expensive is it or would it just be easier to get a part time transfer and if i do can i keep the full time caps on it instead of buying a set of locking caps

Well I know the 205 and 249 np are full time, but I thought the 203np is part time. but either way if you put locking hubs on you will need to make sure the transer case is part time or you will burn up the case
Yes you need to change parts of the transfer case(just inside the front output yolk) besides adding the manual hubs.
Mile Marker and several other company's make a complete kit with all the parts you need (transfer case and hubs). Not super expensive and not hard to install.
If your doing it to save gas don't waste your time. Those are 10 mpg trucks any way you cut it..................md
