1966 flexplate external weights

[Edith68]

Hi, need to buy new flexplate for my 66 428 bird.
Do i need a flexplate with or without external weights (w/weight)?

Br,
Tom

You will get more responses with a better title. "1966 Ford Thunderbird 428 flexplate" could mean anything. I will update it for you. Also, we are an all Ford Thunderbird site, so you can omit "Ford Thunderbird" from your future post subjects to shorten the title.

A 428 is an externally balanced engine, so you need one with weights.
