One thing I do know is the ext cab floor pan is different than the regular cab.(I know because I did it) The mounds had to be customized. So the mounting backets would have to be changed regardless. Good luck with your project. :great:
Dreamers I took the chance and bought both of the 2004 Avanlanche Bucket Seats. Success ! They are a direct bolt-on.
Next request, I need to figure out the electrical from the 2004 Avanlanche to 1999 Silverado 2wd, ext cab. I've noticed the Silverado has a single connector with 3 wires. The Avanlanche has two connectors, one large and one small. Anybody know how to take this challenge, HELP !:glasses:
