Congrats and welcome aboard. The car was purchased minus suspension, that all went onto Bretts Kirkham.
The Shelby differential is similar to Jags but the housing has pinion mount bosses. All the parts you need for 4820 are readily available. I am putting 4772 back together from a worse condition than yours. You have a good starting point for your project, we'll be talking more about it I'm sure.
