I haven't, but I have an NOS one if you'd like it. Do you have the crankshaft and bore diameters?

The original typ is a simple mechanical seal that works very well.
Care needs to be taken when installing the timing cover to make sur that the opening for the crank pulley is entered.

Property installed that factory front seal is about as close to perfection as you can expect for a mechanical contrivance. It just makes absolutely no sense to consider a conversion.

These were actually good seals that did their job well in properly maintained engines. Of course, for engines that have sat for decades, overheated or improperly maintained, they are likely hardened to the point that they are useless. That said, one of the reasons that this type of seal was used was because the shaft was keyed so you can never use a conventional seal with that!

You never use a seal on the crankshaft itself, they are all keyed in every type of engine, the seal runs on the pulley.

Wrong, the seal does not run on the pulley, it seals against the timing gear cover.Again, to repeat, it is a simple mechanical seal that is functionally the same as very sophisticated mechanical seals used on high pressure centrifugal pumps.

Once again .wrong . The crank pulley is keyed to the nose of the crankshaft and extends inside the timing cover to butt up against the crank timing gear and retain the metal housing for the seal . The original type seal does not touch the crank pulley surface but rides against the inside of the timing gear cover with a thin film of oil between the circular seal face and the timing cover. As stated by others, the original type seal works very well.

That was my point. Putting in a conventional seal with the shaft running through it, the key slot wouldn’t seal but the factory seal works very well.
