k by backseat for my 88 samurai has no rear hookplate so its unsecured, and there is only the female ends of the seatbelts anyhow.
 how easy is it to replace whole seat with one from tracker? or can i use the male ends of the belts from a tracker seat and save the $$ at the wreckers

If you are only missing parts but have the backseat you are way ahead of the game... just source out the few missing parts and you are done... If you want the parts right now, I would call Petroworks or Trail Tough to see if they have them available.

You can find parts on :
Craigslist
Ebay
Try forums to see if anyone is selling the parts you need :
Zuwharrie
Zukikrawlers
Try Samurai parts vendors:
http://petroworks.com/
http://trailtough.com/

Also call Hawk (1-888-SAMURAI) They will have what you need.
