Newbie Needs Basic Info, 1970 C-10

[Tripp In Clemson]

I've begun putting together a 1970 C-10 SWB Step Side. It has a factory V8 and manual column shift three speed. A previous owner decided to convert it to automatic trans but sold it to me before he got too far with the swap. I'm trying to get it put back together as it was built.
I've picked up most of the parts I need locally, but I'm having a real problem with the shifter rods between the trans and the column. I believe I found a post on this forum indicating the rods for the V8 and the L6 are different. I'd like to know if that is the case as well get a little advise about identifying the engine and transmission so I am certain as search this site that I'm finding the correct info for my truck.

There is so much great info here, I just need a little nudge so I can find the proper path through it all.
