Incorrect tie rods-I need help

[GoodOleBoy]

My truck is a 1970 C10 that has been converted to 4wd.
I went to replace tie rods and foolishly threw out the ones that had been in it before I got the new parts.
I had done wheel bearings on the truck and I found the right wheel bearings were the same as a 87 chevy V10(k10 basically)pickup. So I assumed I could use the same year for the tie rods and found out that wasn’t the case due to the tapered holes on the knuckle being too big.
How can I figure out what are the correct tie rods to use with my limited knowledge of what was on there?

Lets see if I can figure out how to add an image....

Use a 1983 or 4 K10 as a reference, should getcha where you want to be
