bug rear hub spacing side to side

[najort 32]

This is a simple question. I have to know what the measurement is for the spacing between axle flange hubs from one side to the other .I lost the measurements and the car is apart. I need this because I am building custom controll arms I think itr is around 51"

Hi

I measured the rear my 73 IRS 1303, it had Type 3 rear drums that do add a few mm, but the distance whel bolt face to bolt face was 1405 mm
