Making my 5x5 pattern a 5x4.5

[Loanranger]

Wow you got numbers backwards.

What's the 12 bolt out of? I believe the trucks to be 5 on 5.5 (2wd) or 6 on 5.5 (4x4)

A front D44 will be a 5 on 5.5. Only 5 on 4.5 is a 78-79 Ramcharger, or Jeep TJ Rubicon.

That would actually be any 75 to 79 dodge half ton, not just the 78-79 ramchargers. But they won't work, because they are a passenger side drop.
