GMRS okay with RR permit?

Hey all! New to the forum - learning some great info already. I’m looking to invest in some GMRS radios and have a question about the license. I currently have a Restricted Radiotelephone Operator Permit FCC 753-Part 2, issued back in 1994 when I worked in commercial radio. Form 753 has now been replaced by Form 605, the same one used for GMRS applicants. So, anyone know if I’m good to go using GMRS with the older (but still valid) RR 753 permit? Thanks!

I called the FCC and the answer is no. While they both use the universal form 605, RR and GMRS are two different classifications.

I have - Deal directly with Lance or Deborah. They are good people.
