left back wheel suspension

[wander]

Onderstaande e-mail kwam bij mij binnen. Kan iemand deze R4-rijder uit Hongarije een eindje op weg helpen met advies?
Alvast bedankt!

Hi!

I'm Attila Rindt from Budapest, Hungary. I have two R4, one from '84,
one

was
broken, that's a frequent mistake on this typ. My question is that
anybody
have any drowings or any alse source which can help me to can rebuild
this
suspension corectly.

Best regards: Attila Rindt
