Front spindle help

I sure hope you don't get fed up with all my questions, but this is the greatest information source around, and with the search not working, this seems to be the best way.

I have a 1970 3/4 Ton with 8 lug spindles. I have a chance at getting all the front end parts from an '87 Chev 3/4 Ton van with 8 lug. Will those spindles fit my upper and lower control arms? What would be required to have them mount on my '70?

Thanks
Tom

Looked at Hollanders and an 87 3/4ton van is not a good swap. I have attached what Hollanders shows will work for a 1972 3/4 ton truck (I used 72 since it would have disc brakes):
