1964 Dart Owner - In Over My Head

So, just an update and two quick questions....

Took the Dart out on a decent road test today. Car handled great. Just a few thoughts... Man that slant six is gutless climbing any sort of hills! (I know, it's more likely the gears in it.) Got a bit hairy for me on one mountain we had to go down. It's a 65 mph road that starts a huge downhill incline that turns into a sweeping right hand bend. Not too bad on it's own but our lovely DOH built it with the banking throwing you out of the turn.

I thought I had gotten the gas leak sealed up right and proper and it doesn't appear that way. As I was filling up this evening I made a nice ecological disaster in the Sheetz parking lot. So I can't figure out which gasket (grommet? I've seen it called both. The tech manual calls it an oring.) that i need to order. Classic industries lists three different ones that all look different with different dimensions. Also other shops to look at? Classic Industries wants as much as the gasket for the shipping!

The other question has to do with the steering. Being that it's an old car, I know that taking it into a shop for handling issues is a hit or miss proposition. So I noticed that I've got a bit of a shimmy shake to the steering when braking. Is this a brake issue or more of an steering issue? What to look for and what should I start with?

Thanks for the help and patience with a young guy, learning his way with a classic car.
