Hi Gary,
I know of no specific MGTD Replica Clubs other than this forum. I’m sure there must be some car clubs in the Tampa area that are kit car friendly, maybe even a kit car club?
My buddy (retired) lives in Wesley Chapel, northeast of Tampa. At least you have nice weather year round for “the wind in your hair and bugs in your teeth”!
Good Luck, Mark “Pink MG” Hendrickson
