I think my question can be answered in an email if you like. For my next order , I need hose clamps. Rad size & heater hose size. You have a large selection. For Cadillac , what styles were used in the 30’s , 40’s 50’s & 60’s. I’ve bought tower clamps from you typically used in the 60’s. I’m currently restoring a 49 cad now. I have 48 cads from all decades.  Thx. Steve
