Hello;
I have a 71 Cuda, currently set up with a Wildwood rear disc brake kit. It is impossible to use OEM 15" steel wheels of any kind, which is what i want to do.
The Doctor Diff kit is not going to be available for three (or more?) months.
Locally I can get a barely used Inline Tube /Pirate Jacks kit,

1966-74 Mopar Rear Disc Brake Conversion With Standard Rotors https://www.inlinetube.com/products/dbk834

Anyone have any experience with this kit, good or bad? My experience with inline Tube is that I will not be able to get any decent information from them, and the web page is pretty limited.
Any help is appreciated, I want to get this car back on the road!
Thanks,
Mark
