Seat diaphragm fitting-anyone done it?

[Johnwindwood]

Guys

The seat diaphragm on our drivers seat collapsed some time ago. I managed to get a new original replacement and have started to try to fit.
Seat is apart, old diaphragm off, cover connected via wires to the new diaphragm. Next step is to connect the diaphragm hooks to frame.
The problem is that I need to stretch this thick strong rubber sheet about an inch and a half to get the hooks in. I've tried pulling with pliers but that just doesn't cut it.
Has anyone ever done this job? If so, how did you get the hooks in?
Many thanks.

I made a "capital J shaped" puller to get exhaust rubbers into place. What about a tent peg puller?

Hi, could you let me know, were to get hold of a seat diafram, as I need to do mine. Thanks.

Similar to Pete - I have a J-shaped tool for installing springs on a trampoline that enabled me to apply sufficient load.
