Which models came with 5x4 wheels ?

ok thanks. Just the spindle was different 9” to 10” front drums.

Yup. Well, 3 drum spindles. ‘67-‘72 9”, which is different than ‘67-‘72 10” but both use the small upper ball joint. ‘73+ 10” is different again, using the large upper ball joint and the larger 73+ wheel bearings. But they’re all SBP.
