27 T roadster upholstery questions/help?

I'm still thrashing on this T roadster to get it ready to drive to the hamb drags in less than 2 weeks. We're working on interior and have questions. I'm using a plywood seat back and have the original style wood tack strips in place. What has everyone done for the side panels that go from the seat back forward to the door latch post? What did everyone use to attach the upholstery to at the seat back area? I have very little experience with interior work, so pictures would be a big plus.

Thanks

 

here is an easy plan of attack
get some clear plastic (the kind of stuff us northernes use in the winter for our windows) and stretch it flat and tape it to the pannel you want to make interior for
outline it with a sharpy
cut it out
tramsfer it onto a piece of 1/16 plywood
then cut it out with a jig saw
get some thin foam from joeann fabric
spray adhesive
cover with vinal also from joeann fabric
staple and done

I used a cage.
