Can you help? Driveshaft Question....

Posted by Chris on May 30, 2021 at 8:55am 1 Comment


Newbie to the group here - we have already found tons of invaluable information on the board, so thanks! We are restoring a 1963 Series 62 Convertible. We are wondering if anyone knows of a source to buy the propellor yoke flange (that bolts to the pinion flange) for the driveshaft? One of our ears partially broke off. Not sure if we can buy just the yoke flange as an aftermarket part, or if it has to be rebuilt by a welder/fab guy? Maybe a salvage yard for a source? Again, any…

63 Trunk detail

Posted by Bob Pontius on April 8, 2021 at 3:07pm 6 Comments

Jason, I liked the detail and information you have provided. I would like to do mine similar to yours. Can you help? Do you have trunk material? OPGI is sending the trunk product for my 63 Fleetwood. But it does cover the entire trunk as yours was done. If you do not have can you give me a reference? Thanks!! Bob
