Steve, all of your questions are welcome here. And, don't worry: if folks got kicked off for "stupid" questions I'd been gone about 5 years ago.
You are very lucky indeed to own a '57 MGA coupe, a most beautiful and rare car. Not only are MGAs a good investment, but they're tons of fun to drive and own.
Please, if at all possible, include photos of your restoration effort. It's for us here, and for the world to see!
And, don't stop asking questions . . . :thumbsup:
