7.25 differential conversion

Does anybody make axles for a 7.25 “ rear end to swap and convert from a 5-4” bolt pattern to a 5-4.5” ???
As far as I know, the only way is to redrill the SPB axles, or swap the complete 7 1/4 rear axle assy from a later "A" body with the LBP.
PS: The later LBP axles, will not fit the SPB housing.
