Mutt's37Buick

I just inherited a 1937 Buick Roadmaster from my Grandparents, who bought it used in 1942. My grandfather (Mutt) owned Ace garage in Denver for over 30 years. I played in the Buick as a kid and my my Mom remembers riding in it when she was young. The car is rough because it has been parked for 60 years and 25 of those years it was outside. I want to turn it in to a slightly hopped up, safe driver. I have done all maintenance on our cars through the years (over 35 cars) including rebuilding an engine, changing transmissions, and clutches. I have done some minor bodywork and interior work as I completed four van conversions in the 80's. I have not done any engine, transmission, or suspension conversions to date and this will be my first street rod. This is going to be a challenge, no doubt.
Thanks,
