Hey Bob C,
The 4100 body will not fit into the ChemDip gallon can.
I used a large metal and porcelain pot. There is a parts basket that comes with the gallon can and all the small parts will go into that basket and into the gallon can.
BTW, if you need any JPGs of the 4100 for reference, click here:

These are the JPGs of the rebuild and restoration of the Autolite 1.12 4100 C4AF 9510 DG that is going to soon be installed on "Ms. American 3.14159", the ONLY 1964 Ford Galaxie 500 4-Door, Hardtop, Police Interceptor on the whole World Wide Web.

Hope you are well.
