Will a 70 Monte Carlo split back bench seat bolt in my 70 GS 350 ??

I found a seat online and within driving distance out of a 70 Monte Carlo. I know the Chevelle/ Malibu will bolt right in but will this one?

 

I would say yes, considering the '70 Monte Carlo was also an A-Body.

The "tale of the tape" should verify this.

 

Yup, the Monte Carlo uses the same seats as a Chevelle and other A-body cars, just different upholstery.

 

rear seats would be different.
