'09 Dodge Challenger RT, '84 Cadillac CDV, '05 Ford Crown Vic Sport
I was just wondering what the gear ratio in my Cadillac is. It's a 1984 Coupe DeVille with the HT4100 and the 2004r Automatic Overdrive. I don't think there was a trailer-towing package in '84. It is the basic 7.5 inch 10-bolt rear axel. I want to put a limited-slip in there when I do my engine swap later this year, and I want the same ratio. :burn: Also, how many splines do my axels have? Thanks for any info.
