Jaguar rear end
I tried doing a search on this but it came back as no results found. I saw a 54 Chevy pickup the other day that has a Jaguar rear differential mounted in it. It was quite a neat set-up. The guy told me what years was the most desirable to try and locate but I forgot what he said. I am thinking around a 1978?
Does anyone know what the most desirable years for the Jaguar are? I liked the way he had it mounted and the easy access to the disc brakes. Removing the rotors might be a hassle, don't know for sure. I don't need one at the moment but one of these days if I run across one at a price I can't resist I would like to know if it is one of the more desirables.Ed in Jeffersonville, IN

Ricky, no I haven't found anything particular so far. Strange, this is the first reply I have got pertaining the post about the Jag differential. It sure makes a nice looking setup. I agree about the 69-79 because of the gearing.Ed in Jeffersonville, IN

Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
