So one of my spindles is screwed. I took it off and went to the auto wrecker to get a better one but could only find ones with five bolt holes and mine has six. Will the knuckle that the spindle bolts to work either way or what can I find a 6 bolt hole spindle in? Thanks for the help

 

Here are pictures of 2 different ones. Without going to where these are to look, from the pictures it would appear that one is 5 hole and the other looks like it would have 6.
One of those is off a 92 (early style) and one is off a 95.
The change to the steering knuckles came in 93/94 when they changed to slide bolt mounted calipers. So I would guess that you would want to look at trucks with the same steering knuckle/ caliper mount setup as yours. 93 (92?) and older/ 94 and newer.
Hopefully that's right. I'll be sure to have a closer look next time I'm there.
New spindles can be ordered from broncograveyard.com (but they're one of the more expensive pieces on the front end).
I believe yours are probably the older style, back to 80 but stay away from 87/88 top hat style unless that's what you have.

 

The 6 bolt one came from the 92. The 5 bolt one came from a 95.
