I also have a 63 Jag Mk2 with a Dana 44 so I bought a rear end from a 1959 Ford F150 because it had a Dana 44 that had a Trac Lock posi in it. I pulled the ring and pinion and carrier with the Trac Lock out and ( stupidly) junked the axles, brakes 10 inchx21/2 inch drums and backing plates. OH WELL.

Why Ford used a Dana in 59 when the 9 inch had been made since 57 is a mystery to me, lack of supply, using up old inventory, who knows?

Just thought I would throw this out there for general information so next time your looking at old parts keep this in mind. Pete
