One possibility would be to remove everything from the dash (gauges, dash pad...) then the front seats, front carpet and kick panels. Place cardboard on the now bare floor areas and use aircraft paint stripper in a well ventilated area.
Finish with a nice sanding then primer and paint.
Sure others will have their suggestions - just getting the ball rolling for you 
+1 Jeff!
Try to find the stripper product with the highest concentration of
methylene chloride as the active ingredient, Ace hardware carries a good spray bomb type called ''Tal-Strip''. Use a respirator if working in tight quarters, and watch out the overspray.
Keep a wet towell nearby if you get it on your skin, water kills the stripper quickly.
Carefully scrape excess paint away while the stripper is still active. Scrub off any residual stripper and old paint with rags,steel wool, scotch brite, or wire brush on a drill, untill it is only clean bare metal.
Any remaining specks of old paint will hold stripper, and will most likely cause the new paint to peel,so be through when cleaning the residue.
I wipe the area well with lacquer thinner, or you can buy a product designed as a wash to kill any paint stripper that can help avoid disaster.
Always read and follow the directions on whatever products you are using.
