Try calling Jeg's with that P/N, I called on a valve spring that they did not list in their catalog, gave them the Mopar P/N, and they gave me price way better than MP's.

If there were more of a market for MP parts, you can bet that the big warehouses would be buying in quantity and the price would come down. MP's cost with their overhead to stamp out 10 sets of valve covers is probably only marked up 15-20%. Parts are usually a cash cow for on OEM.

Also, Mopar has kept up sponsorship of the P/S teams, the Hemi shootout, NASCAR, and other racing over the years, even through near bankruptcy.
