Those paddle switches are getting as rare as unicorns. $100 for originals in working order is reasonable to me - if you have to be original. I'm not sure if they'll fit but these were use by pontiac in the late 80's - early 90's: https://www.ebay.com.au/itm...6:g:ZP8AAOSwr81UNxLo
. Seem's like I saw a Fiero with a late 80's - early 90's steering wheel someplace. I think the wheel may fit but the hub depth was different than the hub on the Fiero.
Alternatively, you could look for a Fiero GT steering wheel. I see those occasionally on eBay & Craigslist or you could use this: https://www.ebay.com.au/itm...6:g:ODAAAOSwjKFZQZC-
Good luck wtih your search.
