81 lug pattern

Ok guys, 1981 F100 Stepside with inline 6. Read every site there is, and some as you would expect are contradictory, they show me 8 different ways to measure and everyone measures different. Want to buy wheels online, specifically the black V5 Cragar from Jegs. What bolt pattern do I order?

It depends, F100's were available with two different bolt patterns.. I believe it's 4.5 and 5.5

On a 5 lug you measure diagonal from the center of one stud to the far side of the one across from it.

And like Sw1tchfoot mention there are two Ford bolt patterns you have the large standard 1/2 ton Ford pattern which is the 5 x 5 1/2". And the smaller car bolt pattern which is 5 x 4.5".
