78 f150 steering boxes

[78_f150]

I have an old 78 ford f 150 4x4 with the extended cab. My steering box is broke and im haveing a hard time finding one that has four mounting holes. My question is will a 3 bolt box bolt on and work since i can find them ? Thanks for any info.

if you want to drill new holes a 3 hole would work.
