hi, how do i know which clutch to get for my 1969 beetle. (might be dum question but i know nothing about cars)

not a dumb question ..... make sure its a quality German brand not tawianiese of Brazilian

you make a pay a little more but worth it in the long run..

And just quote the year model.
The cheap pressure plates dont locate in the flywheel properly(sloppy fit),
which can wreak havoc on the balance of the engine.
I think this is the main cause of a pounded out number 1 case tunnel.
