Thanks All ! And yes, round pad. Ok, pennyman, if you say so ,,, LOL
(But you've never let me down before)

I tired to pull and pry a bit, but it seemed awfully tight and I didn't want to break anything.
But I'll give it a go ! Have to get it aligned after replacing the front end with much lower components.
And the alignment guy wants the steering wheel centered Before he starts. Seems odd, but if that's what he wants ,,,

Ok, I'll let you all know what happens.

(the next question will be about the best replacement carburetor, was it a Weber ? have to search)
