help need a steering coupler repair kit

FWIW, Dorman part number 425-253 (less than $8.00) appears to be exactly the same as what's being sold on ebay for $20-45. (Also the same as the base kit that Bouchillon or Steer and Gear is selling). The Dorman catalog lists it for vans. I bought one that I plan to install in my '69 C-Body. I've compared the parts. With the exception of the ID of shaft hole in the rubber seal, everything is identical. Heck, even the kit I bought off ebay years ago for my Duster had the orange seal with the hole smaller than original.
