273 Front Main Seal Question

Doing a Timing Chain!
How do I replace the front seal in the old style timing cover?
I thought it would be obvious, until I had it in my hands...

I can see the seal. It's the 1/4" ring between the balancer opening and the timing cover. You need a drift punch and a hammer. The new seal should be flanged like the old one and only goes in one way from the backside. A 2x2 block of wood and a hammer works well. Get it started and work your way back and forth.
