anyone know the width of a 49 chevy rear?

Anyone know how wide a 49 chevy car rear is from drum to drum?

 

I don't know the D-2-D measurement but this link to Suspension Measurements may help.

 

My 51 is 60" D2D. I believe they are all 60" 49-54.

They are 60" stock.

 

Looking for a swap?

S10 4x4 is closest at 59" - second gen Camaro is 61.5 - I forget what the 55-57 Chevy is but they're close too.
