47-59 Napco Transfer Case Mounts - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So the rubber isolators worked perfectly. I did make steel sleeves for the ID of the isolators- the tops needed sleeves with 3/4" OD and 5/8" ID and the lowers needed 7/8" OD and 5/8" ID. Easy enough. The top isolators have a lip that sits down into the steel bracket, I had to trim off some excess rubber here to get it to fit properly but it was not unexpected. One step forward on this restoration. Having some engine issues now with bad news from the machine shop but thats another story altogether.
Anyway- here are some pictures.
