Hey, Chris in Illinois here. Well, it appears this forum has been here a while but I just found it.

I picked up :D an 86 K20 a few years ago. I'm finally getting started on getting it going. The kid I bought it from was mid process swapping the diesel for a SB 400. It's basically a short block so I've been trying to get parts to finish out the engine.

So, there's a newish water pump on it with no studs, so I need to find those.

I already installed a new alternator. I have a new power steering pump and hoses. They arrived yesterday, I'm hoping my ebay bracket will fit the small block and ps pump with reservoir and hydro boost.

I still need to take the, what I assume to be, original radiator laying in the bed in to a shop for cleanup and repair if needed. Also, i have the fan and clutch that I assume is from the diesel. I'm not sure. I also don't know if I can use the fan and clutch from the diesel on the small block...

Lots to do, but worth it. The body isn't great but not terrible either. The goal is to get it up and running enough to make a few off-roading memories with my son, then hopefully restore it with him to be his when he's old enough.

I'm looking forward to learning a lot here from folks that have already done all this and hopefully will not repeat all the mistakes already documented here, along my way.

Welcome! You should be able to find the studs at any auto parts store from Dorman. Make sure you get w/p studs and not Carb. I see a lot of people using carb studs and they aren't quite long enough to get full engagement of the thread.

I went to autozone and oreilley today and neither could find any for me. The guy at oreiily said he just uses bolts through from the fan clutch.. :banghead:
