First, welcome Storyboy.
For the most part, a standard (i.e. original) MG TD top and side
curtains will not fit a TD replica.
You can also try MG Magic. Search the site, you’ll find lot’s of threads with MG Magic’s info.
You could also go to a boat place and have a top sewn.
It is possible to mount a real spare on the fiberglass deck. But you need lots of steel support behind the fiberglass. The fiberglass by itself will not be string wnough to support a spare.
