Bench seat to shag bed conversion Qs..

[littleB]

Hi. This is my first post here, I have a '90 c-10 reg. cab with that basic non-reclinable bench seat. So the back only folds forward, not backward.
I want to get the back reclined flat with the seat, and I'm sure there's room for this if the bench is slid all the way forward.
How can I modify the hinge to do this? I saw there is no ratchet or spring there, but I can't see it very good.


PS: I swapped my steering column with a tilting leather wrapped one from a Fiero, so The cab will be very accomodating.

Thanks.
