Hopped in the speedster to return home, and the darn seatbelt wouldn't extend. After SLOWLY feeding it belt, I SLOWLY pulled it out. No joy. I repeated the process while tapping on the retractor. No luck, again.
My dog and I both rode back home without seatbelts and I felt like I was replicating the vintage speedster experience. I didn't like it.
YouTube has a video on how to take the retractor apart and do nothing and it will work again. I'm fine with working on anything on my car except the transmission and the seat belt retractors.
I ordered a new one and am making a list of things to work on while I wait for delivery...
