One thing I have been looking for is a rear end out of a 1975 Lincoln Versailles. This rear end is a large Ford 9 inch rear end with the largest bearings available from Ford and it has factory installed brake calipers. With only a few small modifications it will bolt right in the GT350R. This enables me to have four wheel disc brakes which are a major requirement for the rugged La Carrera Panamericana Race and is far better than using aftermarket rear brake caliper systems which tend to cause brake failures. (Something we don't need.)
Well, the great news today is I struck gold and not only did I find one but in fact it's located in Sacramento California which is only a couple hours drive away and makes for an easy pickup.
