Any of these two work for you?
Edit: Link didn't work. Hayden has two that fit your '71. Maybe check out their website?

Do a search on this forum in the C-2 section. I know I have read posts about a clutch rebuilder that members use. Jerry

I used kirkconnellcorvettes.com for my 71 LT1 Shweizer fan clutch - got it back in a week from date I shipped it to them in Florida.
Has been on the car for 2 years now... the amount of air it moves now is exponentially higher when compared to it's prior to it's rebuild. Sounds like a tornado.
Because they are crimped aluminum -
They tig weld a new lip on the clutch machine it on a lathe or mill install new seals and bearings refill with oil and recrimp.

Drive your car to get the engine warmed up completely. Bring car to a stop, but leave engine running. Open the hood so that you can see the fan as it is rotating. While watching it, turn the ignition OFF. If the thermal fan is OK, it should stop in 1-3 rotations. If it just keeps spinning, the thermal unit is defective.
