3 to choose from…..these are from my dads shop so I don’t know the history…..might even be Chevy not sure…….all three spin freely…..one is marked 1.3900, .8241 and the third 1.2020 which has a notation of 70 Chevelle 4.10 gears……not sure you’ll have to look up your application of what you need. $99 plus shipping. All 3 are made by Stewart Warner. PM or text 661-203-6953. Thanks, Dave

 

Those are offset inline adaptors. The 90* looks like this.
