68 fastback USCT Mini tub kit. Any good?

I have ordered USCT spring re location kit and wondering if i should get them to send me a mini tub kit at same time.

Questions i have:
-Do i get to keep my rear seat?
-Is the USCT mini tub kit a good product? or should i be looking elsewhere?

Thank you in advance
