rear lower corner panels

does anyone know where i can get replacement parts for the bed?? i know these specific pieces are tacked and press fitted into place, but both of them are pretty hammered...and I am looking to buy two new replacement panels. They are the very bottom two corner parts on the back end of the bed..i need to replace them before I go ahead and mold my roll pan. Shoot me a PM with any info, thanks alot guys!

the parts are available thru Isuzu still
66.03 EACH

the part numbers are:
PANEL; OUTER LWR,RR BODY - RIGHT 8-94450-408-0
PANEL; OUTER LWR,RR BODY - LEFT 8-94450-409-0




also i have a rather clean 90 Isuzu pup bed for 300.00. no rot, very little rust on the inside seams on the wheel housing , like MINOR.
