So yesterday as I was picking up a friend to go to the local pool hall, he sat down in the front passenger seat of the '66 122S, and the back portion of the bottom of the seat gave a bit of a snap and sank a few inches. I'm assuming this was the webbing of some sort under there, but the guy that owned the car before me re-webbed the front seats no more than 6 months ago. I'm about to go pull the seat out and see what's going on under there, but I thought i'd check with everyone here, seeing as you have probably had this happen to you to. Any advice on how the webs attach under there? I hope I can reuse this one? Anything will be appreciated.

I'd also just like to say Thank you all for being so quick to reply to my posts in the past bit, it's really helping alot. Volvo owners have seemed to bit a bit more helpful than when i used to look for help on my '68 Pontiac Firebird.
Thanks in advance everyone.
(sorry if this was a bit long)
