Mid 70's to 79 were full time with an auto transmission and part time with a 4 speed. 1 tons were part time. The 4wd trucks sit higher because the spring hangers are longer than the 2wd.

I havent messed with it much So mines probably full time 4 wheel drive?

andrewmp6 · 12-13-2015, 02:22 AM

If its a auto its probably full time aka np203

It dosent really run would it just be easy to take the entire front clip off take the guts out with a cherry picker with the tranny attached and stuff everything from a doner silverado in there if i was gonna do a LS swap?

what gear ratio would it likely have?

andrewmp6 · 12-13-2015, 04:09 AM

It can be either 4.10 or 4.56,If you want the cheat sheet i use http://www.chuckschevytruckpages.com/73-87specs.html If your gonna part it out keep that winch bumper it looks like a old warn one you could make a few bucks off it.

DustyNova · 12-13-2015, 04:31 AM

Where do i look on it to find out the gear ratio?

andrewmp6 · 12-13-2015, 07:28 AM

Look on the diff bolts see if the metal tag is still on it,If not you might have to pull the diff cover to find out.

stock ratio = 4.10:1, optional = 4.56:1
If not called out as 4.56 on SPID, it's a 4.10 (at least that's how it was born)
Even if yours is an automatic trans, it has what look like Warn lockout hubs installed, so it's been converted from full time to part time if it was originally full time. Google a few threads on here about the conversion so you know what the different selector settings are actually doing for you - they are not doing what they are labeled if it's a conversion and the t-case shifter is original. Just something to be aware of and understand before you start driving it.

the winch is a Warn 8274, they are awesome winches, it is worth atleast $600 if it works,not including the bumper
