5 bolt pattern

whats the measure of the original 5 bolt pattern for a 87 half ton pickup 2WD?

5 on 4-3/4 I believe...  Pretty sure that was GM's standards for the 2WDs, S-10s, Camaros, etc. of this era.

I'm pretty sure its the 5 X 5" pattern.  I'm pretty sure that's the standard from '71-'98 for the half-ton trucks with the 5 bolt pattern.

That's what I have on my 79, and that was what was on my '83 when I had it.  When I look at the chevy rally wheels on ebay they also say the same thing.  

5 X 4 3/4" was mainly used on passenger cars and S-10s.
