aluminum

When I was at the wrecker pulling my 'new' s197 seats, I noticed the doors on a close by 2000 really felt lighter than my doors (1996). My questions are; One. Are there weight differences? Two. Will 2000 bolt on a '96? Three. Were they made of different steel? maybe aluminium? Thank you

Want to buy, a used set of aluminum heads, they can need work, will consider any brand and size.

I have a set of 2008 -2012 OEM 18" factory wheels in excellent condition. No marks what so ever on the wheels. Flawless and they include the TPMS and center caps. $450, prefer local pick up. Live in the Seattle area. Its time for them to go as they are taking up space in the garage...
