Howard, my opinion only, on your SLC ...
TX, as a default, will go by whatever the CA title says it is. I believe you never lose your SB100 certification, if anyone ever wants to take it back there. When it is being titled in TX you will also want to register it for "Custom Vehicle" plates. This involves the prior action of getting an ASE Master Technician to execute TX form VTR-852 (ASE Safety Inspection and Application for Custom Vehicle or Street Rod License Plates). And your insurance card must reflect that you are a replica of some vintage car. Then you will never need another inspection.
If you want to wait till you move to start the process, you can do that. See the adjacent thread (
Texas ASVE Title ...) for the checklist. It takes some preparation. You will be titled as "2015 Assembled Vehicle, Replica: 1968 Ferrari - or whatever" you will owe no 6.25% TX sales tax on the purchase. You will have to figure out what you are a replica of, I think. Pick something similar that existed back when
Good luck!
