1973 Blazer-rear bumper backet spacing

[JW-Tex]

Anyone know the spacing for the rear bumper brackets on a K5 Blazer 1973 (where it attaches to frame)? I am looking at a bumper on Facebookmarketplace and need to make sure it will fit. The blazer is at the hunting camp a few hours away and I think I need to jump on the bumper if it will fit.

It is an aftermarket/homebuilt bumper looks like the insde of the barckets are 32.75 inches apart.

Thanks in advance for your help!

Literally just went and measured this. Looks like 33.5” from inside to inside frame rails.

Mine is a ‘75 just to clarify.
