Based on advice here on repairing my front sagging seat I found a whole warehouse full of parts in Rexdale, (Toronto). Very helpful and loads of stuff.

The website says they only deal with wholesalers. Did you buy parts direct from them?
If so, who did you contact?
Thank you.

Sorry, I only looked at the site after. They have a parts counter you can walk up and buy from. I bought a 124 seat, mirror and Porsche 944 oil pan gasket. I suppose you could sign on as 'yer own dealer". Folks in TO should put this place on their Fav list.
