Non genuine R/H repair section
for wind up window type doors this is the lower 2-3" of the inner skin and the bottom of the door section that usually rusts out-includes a lip section where the outer skin flaps overlaps for fitment--new panel in 2005 but already a good seller but you will need to be experienced to fit this repair panel.
See
MS33R for the bottom section only and lower lip with a few vertical inches for all of lower door skin to attach to.
Technically you cannot fit both MS33 and MS34 together--MS34 being mainly for when bottom of door and inner skin have rottted-MS33 when just the bottom has gone by the drain holes
