Found out today that there is a different sprocket for the early 500's. Now just have to wait until it gets here. All the other parts are the same; drive sprocket, timing chain, seal and gasket. I installed the seal in the case, from the inside. That really seems weird to me but that's how it is shown in the shop manual and that orients the sealing lips in the right direction. I also cleaned up the nuts and washers used to mount the housing to the engine so It's all ready to go when the parts get here. Spent some time designing and making patterns for the engine lid hinges since there is none available anywhere in the world for less than a million dollars . GGGGGG Wonder what happened to all the ones on the cars? Must be like the hood trim, I've been told those parts fell off when the car was driven off of the dealers lot. Also did a little dent removal on the rear bumper prior to sending it to the chrome platers. Mostly just puttered around in the shop today, waiting for parts.
