Yeah,
I tried the after-market door panels too. You had to work to get them to fit, and they felt like hard plastic, not like the originals. If your originals aren't hardened, or "chalky", then I would dye them with S.E.M. dye. I finally did that to my originals and couldn't believe how nice they turned out. Rev has a thread where her and Redline restored their panels with S.E.M. products. I can look it up for you if you are interested.
