Tom Parrish's tops fit well and look good. I've sold a bunch of 'em in past, to fit BMC/Leyland and Alfa Spiders.
That said, the factory ones are somehow "classic" looking and a bit more period appropriate. If you've a choice (and if so, I envy you) go with the factory one.
My tuppence-worth, only.
