32 pickup seat back mounting

[Ideucev8]

How is the seat back mounted? I have done a search here & on the web, some pics show 2 lower mounting brackets & some show 3. Do these brackets just push through the upholstery?
Is there meant to be mounting brackets at the top? It looks like it may of had something around each side across the top of my original seat back spring, and a hole in line in the body wood for a wood screw. If so would anyone have a photo of this please.


Thanks, Phil

H; the seat springs used at least two hangers screwed to the nr top of the verticle wood strips in the cab back. Newc

As shown below. Two below and three on top.

Thanks for the replies. Do the top ones stick up through a slot in the upholstery or sit on top of it & go around the back?
Thanks Phil.

They're behind the upholstery attached to the back of the cushion spring assembly.
