YA SEE I HAVE A 1980 EL CAMINO WITH AN 87 T-TYPE REAR END. I THINK THE GEARS ARE 3.42. KINDA FEELS LIKE IT. BUT LATELY SINCE I PUT A COUPLE 28in TALL TIRES IN THE BACK I THINK I MAY WANT TO GO DOWN TO A 3.73. SO I WAS TRYING TO IMAGINE WHAT SIZE TIRE THE ENGINEERS AT GM HAD FIGURED TO RUN WITH MY 3.42'S ON THOSE REGALS IN 87.
The only other thing that work into play is the type of transmission the Regals used in 87. I do not have the luxury of an OVERDRIVE automatic. Right now I am useing a th350.
