Re: 90q Seat Belt Question

[Steve Manning <stephenm@ix.netcom.com>]

It sounds like you are fooling with the Procon 10 mechanism...it was
introduced in the '88 90q; it is a purely mechanical system that uses
backwards movement of the engine/tranny in a crash to tension the seatbelts.
I don't know how much slack is 'right'; mine is fairly slack-free
(definitely less slack than yours)......SLM
