Can anyone tell me if the profile and measurements of the normal 70-73 front bumpers are the same as that of the 70-73 RS bumpers?

That is - the depth of the 70-73 RS 2 piece front bumpers is approx. 2.25" from front edge to rear edge. And the height at the back edges of the front bumpers is also about 2.25"

The full width, single front bumper used on the 70-73 non-RS models - does it share similar/same dimensions?

Thanks,

 

they are pretty darn close

 

Can you say with confidence that they're close enough that I could use a section from a normal bumper to repair an RS bumper?

 

pretty sure they are the same
