DogsBurb,that is some nice work on that motor mount.I had looked at those photos before and had wondered why you spend so much time on it,but cross member is the only way to go.Looks like you have a nice way to drop it out of the way for an oil pan gasket or whatever.And thank you for that 5 1/2" number.Now is that number strictly because of a smaller firewall to front spindle dimension on the '51 burb vs.the '74 truck?I am going to have to look at my 2006 chassis to see what is involved in sliding that back for that much,although in my situation it will probably be moving the cab forward,tight to the engine than vice versa,because I don't have any dimension behind my cab to worry about as opposed to a suburban needing the wheelbase to be on the money.
You have a good looking radiator there.That is one thing I will be starting from scratch with.
