Looking for 2.45 or 2.76 ring and pinion

I currently have an 8 1/4” with 3.92 Sure Grip in my 74 Duster with mild 360 and rpm’s too high for interstate. I would like to change to for a better driving experience. My hot rod driving days are over and just want to enjoy easy, quite driving.
Your PM box is full! I can’t send a message. The following is what I writing to you;

“I have a ‘74 Duster with a 8-1/4 rear and 2.45 gears. Would you be interested in a trade? I can meet you in about a half way-ish area. Goggle this zip code, 32950, I’m in mid Florida. You’re approximately 11 hours away. Perhaps somewhere in the middle-ish area we could meet?“
