203 T-case part time conversion

[RattleTrap]

Hello everyone, I'm new here thought I'd better say hi.

I have a '77 K10 (350/350/203) that I'm wanting to convert to a part-time 4WD. I thought I had the parts I needed ordered already until I stumbled on this site. Lots of good information on here, but I wanted to get some verification real quick to make sure I'm getting the right parts. I have ordered a Mile Marker conversion and some locking hubs but it appears I also need a conversion kit for the transfer case. Is this the kit I need?

Thank you!

EDIT - I screwed up the links.
EDIT #264 - I give up, I can't get the links to work at all.

If you go to www.summit.com I have ordered part # MMK-95-32720 and part # MMK-402

I think I still need to get part # MMK-501
Is this correct?


Edit:  I fixed your links -roundedline.

Hi R.T.,
I'm kinda' new here myself.
Yes, you definitely need the MMK-501 kit, as this is the parts that convert the NP203 transfer case itself to function part-time. The other parts (MMK-95-32720 and MMK-402)are needed to convert your hubs to selectable lock-in or lock-out. I had a NP203 conversion in my K20 (79 chassis/84 body bare frame restoration), but it wore out and i then went the more costly route, bit the bullet, and installed a NP205 bulletproof gear driven unit, but these are more costly and requires a new lengthened driveshaft.

You will appreciate the part time conversion, with today's gas prices and also less unnecessary wear and tear on the front drivetrain.
