Here's an accessory starting with a special request from someone who dearly wants one exactly like this. This is a VERY period aftermarket accessory alloy valve cover for the MGA. Notice there is no external flange on the bottom and large radius on the bottom corners. Instead it has thick sidewalls, so it will be moderately heavy. If anyone has one of these they could part with, please contact Del Rawlins at del@(remove-to-reply)rawlinsbrothers.org.

"I'm restoring my dad's MGA, and am reusing the cast aluminum rocker cover that he put on it sometime back in the mid '60s. It isn't like the ones that are available today, and it is kind of a pain since I have to re-polish it, and make a special gasket since the standard ones don't fit right. But, I want the car like it was when my dad had it, so it's worth doing, at least to me.
Now, my brother also has an MGA project, and he's expressed an interest in making it look like dad's. So, I'd like to find him the same rocker cover, if possible. The only other one I have ever seen, was in a picture of the "MGA Hawk" racing special (the one with the studebaker grill) on Barney's site. But, where there were at least two made, there were probably others, so I am hoping that somebody here will have one sitting in a box somewhere that they would be willing to sell me. You'll probably be doing yourself as big a favor as you'd be doing me, since as mentioned, the standard gasket doesn't fit right, and also there is less interior clearance for the rocker assembly than the stock cover has. I'm attaching a picture. I know this is a long shot, but thanks for looking and reading this far".

Here are more examples of alloy valve covers that work on the MGA (or any Austin B-series engine).
