AMD had admitted that its hard for them to make money on the mopar stuff. About a year ago they cut many of the mopar parts from their inventory. They have costs associated with setting up dies to do a run of parts and mopar just doesnt have the demand to do big runs of one part. Then they claim that the parts sit in their warehouse collecting dust, taking up valuable space. That is what they said in a nutshell. The only thing I can see they havent backed off on is E body parts.
As far as new parts, 3" wider wheel tubs for B & E are the only thing I have seen in the past couple years.
I got paranoid and bought all the sheet metal I needed for all three of my cars I plan on doing. One in progress and the other two on the waiting list.
