Rattle/knocking right side bell housing area

The last time I replaced the clutch in my 74 OTS was nearly 20 years ago. I’ve dealt with chatter for a long time but no real biggie. In the last year or so though I get knocking when trying to ease the clutch on take off, almost sounding like something is loose. One other thing; I have felt like the clutch has been slipping upon heavy acceleration in higher gears for a while now. The gearbox is fine and shifts beautifully so i’m pretty sure there is no problem there. Any ideas on what the problem is?

Sounds like a worn clutch disk. 20 years is outstanding for clutch disk life!

Time to get back to work on your E!
