203 (with a part time kit) or a 205?

So my 75 came with the 203, the po yanked the 350/203 in favor of the 465/205. I'm want to go back to the 350, but i'm at a bit of a crossroads. I don't want the fulltime aspect of the 203, so what has anyone's experience with the part time kit been? Also, what are the advantages of the 203 to the 205 (if any?). This will not be a rock crawler, just a camping, light light trail truck and something fun to drive to the drive-in. Any input on this would be greatly appreciated!!
 
The 203 w/ the part time kit has worked very well for me and MattK. An advantage is you get 2lo out of the conversion. On a 205 you have to twin stick it to get 2lo. A 205 is alot stronger and meant to be abused. But for what you are doing i would stick with the 203 and slap a part time kit in it.

Also the 205 off the 465 will not go onto the 350 btw.

That has been another concern of mine, i've never messed with 4x4's before and quite frankly, the whole input shaft, adapter plate, this won't fit that, all that stuff confuses me:confused: . But on the other hand, i hate to go to a weaker transfer case just for ease.
 
The 205 on the 465 has a 10spline input, 350 has a 27 spline output. You will have to get atleast a 350 adapter plate and eigther get a 205 out of another truck with a 350 or spend more money and get the spline adapter from Advance Adapters.
 
I had 203's in both of my k5's. I blew-up one of those milemarker part-time kits, that I had in my 79' plow truck, so that was an option I didn't want.

I installed 205's from 80' th350 K5, pretty simple swap, even the holes in the frame lined up.
 
205 swap is not hard, esp if you already have to do the driveline (which I had to do). if you have to get a tranny, you might shoot for the TH400, mainly for 4th gear.

I swapped a 205 in place of my 203 cause I didnt wanna bother fighting with the differential in the rear, plus I would rather the gear drive vs chain. Let me know if I can help... "I have walked the road!"
 
Now let me just go ahead and open a can of worms here. So, if i go with the 700r4/205, will i need an adapter, also will i need to change the driveshafts to different lenths?? Honestly now that you mention the 4spd, that would be nice, anything to help the gas mileage would be absolutely wonderful!!
 
205 all the way, every day. Would you rather have a case that "should do the job" or one that you know will never, ever, ever have a problem.

All you have to change is the input shaft to get it to mate to a TH350. Then you'll need the factory 350/205 adapter housing (eBay) if the tranny you pick up doesn't have it.

Oh, and you CAN have 2-lo on a 205 without a twin stick. Just don't lock in the front hubs! :D
