Is there a company making adapter u-joints that would adapt GM Yoke to a '49 Pontiac driveshaft? Just trying to avoid butchering & welding GM driveshaft & Pontiac driveshaft together. I will propably change to 10-bolt later but first i'll use the stock rear. I am just installing the 292+th200-4R and the original driveshaft seems to be about the correct length.
Best bet is to take the specs from both and search via a manufacturer's website or Napa or similar, then see what you have to do to get one to Finland.
Thanks for the tip. I have tried that and seems to be that I'll have to go the butchering route. Pontiac u-joint measures 2.339 " between the yoke ears and the bearing outside diameter is 1". I have a spare yoke already for the 200-4R and it measures 2.563" between the ears and the bearing diameter is 1.125 ". No luck this far to find such a conversion u-joint so I think I'll just order a weld yoke for the Pontiac driveshaft.
