Racingjunk Forums - Nostalgia Racing

My Son and I recently purchased a 1955 Chevy that was only recently retired after a life of drag racing since the 60’s. It currently has a blown 505 in it and ran low 9’s in the quarter last season. It has all been freshened up and we are anxious to get started with it next season.
I had Jim Anderson with the Southern Central Division office of NHRA come and inspect it to get it all certified. It is now certified for 5.30 in the 1/8 and 8.50 in the 1/4. I personally am retired and have not been on a track since the early 80’s. But, I was plenty active in AHRA back in the 60's, 70's and NHRA in the 80's.
Our intention is to get this car dressed for the occasion and ready for next season and race it in a Nostalgia Racing circuit (if there even is one). Hence, my question to y'all is just that. Actually a couple of questions.
1. Is there a sanctioning body specifically for Nostalgia/Vintage racing?
2. Can you perhaps provide me with some website(s) that cater specifically to the same, for parts, cool nostalgia stuff, etc.
Any help you provide will be greatly appreciated.
