background:
- I have 98 v70 with V70R interior. The 2nd row seat bottoms have "legs" in the front. The legs have a pivot bar hidden behind them. When you flip the seat bottom up to fold the seat back, the seat bottom pivots on that bar. Well... my bigger seat bottom's legs are broken so the pivot bar is not there. So the seat bottom kinda flops around when you flip it up.
- I found a set of 2000 xc70 seats at the junk yard. It has the built-in boosters. leather is rough and cracked and yucky.
- I want to keep the V70R cushion but have a good plastic frame. So I thought about removing cushions from both frames and putting the v70r cushion onto the xc70 frame.
- I started on the junkyard seat bottom and removed all the bolts and screws. oops. they were for the built-in booster and did not affect the cushion and frame.
- I pried with flatblade screw driver between cushion and plastic frame and not much progress. maybe it's glued on? I don't see any hog rings like with front seats.
here is a pic of the seat from the back... I have no red pieces nor bar that the red piece pivots on. (pic from pelicanparts.com):

here is a pic of the seat from the front/top. from a for sale thread on swedespeed:
