I don’t really know what I’m doing

Nice to hear of someone younger taking an interest in these cars!
There's an incredible amount of knowledge that's shared on this site every day, by some awesome people! I've learned a great deal on this site in the last year, it's awesome.
My advice to you, is if you ask a question, include as much info in it as you can, and pics always help.
Nice car! As for the roof color, I've always hated vinyl roofs, and different color roofs... I like plain body color better. But in the end, it's your car, do whatever YOU like.

I also agree with a few on here, big blocks aren't needed in these cars.. which is funny for me to say, when I was your age I was the guy that always ran big block cars, usually b-body mopars, but I had a few fords in there too (and a GM 429 which I have a lot of fun with guys telling me that never existed). Never had an a-body, but my brother ran a few.. and his 340 4 speed 3.55 gear Duster was one damn fun car.
