73 Challenger R/T bumper jack, lug wrench,spring and stand base interchangibility

Hi All,
I didn't really know where to put this thread Mods, please move it if it needs to be moved. Went to car show in Maggie Valley, NC today and had a great time. A 73 Challenger R/T parked next to my 73 Dart Swinger. The owner and I had a nice chat and it turns out when he bought the car, he found out later that it didn't have a bumper jack, lug wrench,spring or stand base. He is an older gentleman and doesn't use the internet (I know, I know). I am trying to help him find a bumperjack setup for his car. My question is....is the bumperjack design/parts for the Challenger specific to his car or will any 70's A Body bumperjack work? If anyone has a complete set up in very good shape, please let me know. He is a Vietnam vet and I am trying to help him out. Thanks as always.....
Greg
