Mike, I think I would cut the package shelf loose from the seat. Then, add the length to the front where you cut it. That way, you wouldn't lose the shape at the rear of it and it will still fit up against the window nicely. When you glue it back to the seat, you could lower or angle it down.
After my Duster project, I doubt if I will ever attempt another one! I would have never thought that a simple backhalf and engine/frame clip swap would have caused so many problems! I've battled fitment issues at every turn! I did have my interior done. But, when I went to put the body on, it wouldn't fit! So, I had to get the dash loose because it had somehow spread apart before the glue set and made the interior too wide up front. I'm just going to leave the dash loose. There's no way it can go anywhere once it's assembled. The quarter windows now have me concerned. I'm going to check everything out before I polish the paint. The more I mess with it, the less details I plan to add.
hehe, don't do that. you should have been warned that, at least for me, on a pro street car, i work from the ground up. get that chassis nailed down with the tubs in place. always make your tubs a hair bigger than the diametere of the tire so you have clearances for the interior panels. i have re-made the tubs on the super bee chassis a few times. i do it to get the bodu low as i can. i have a 69 dart i was scratching a chassis on, here is one chain of events...
- made the frame
- made the tubs
- tubs too tall, body sits to high
- remade tubs body sits perfect
- now engine hits the ground
- raise engine
- engine too high, hits hood
- lower engine back to origional spot
- make new pan
- cage hits tubs
- rework cage
it can be a pain, i know..... oops, then the build you just did all that work to falls to the concrete cause you put it on a stack of who knows what, things bust, parts fly and it ends up in the box like a misfit toys on an island. i will get back on it sooner or later, here is a few shots of when it was last on the bench. once i get back on it, i may post it up here, we will see.
