The first thing I did after putting the lower dash back on post t56 swap wans rip out the ash tray. Having is slide out and hit your hand when shifting gets annoying. After a year and a half I finally filled the big hole in my dash with a 4 gauge pod. It was a bit of a pain to install. Not a lot of room to get some of the screws in along the side.
Right now I have the SSLED switch, fan switch, Air/Fuel gauge, and fuel pressure gauge. It has room for 1 more if I ever think of another one I want. It's not in the car yet because one of my gauge mounting brackets broke.
The one problem is there is a small gap at the top corners. It will probably be less noticable once it's in but I know it will get annoying. Any ideas to get rid of the gap? Maybe some molding to put around the top where it meets the dash.
