I bought a few left (and right) hand latch - item # is 91-026 and 91-027 - from you. (left and above one on my pictures). Unfortunately, this has slightly bigger sliding head thickness (top portion on picture 8149) than my original one (right and below one on pictures. It lost its blade on this picture). On your catalog description, #91-026 has 5/32 thickness. I think mine has 3/32 or 4/32 thickness.
Can you help me to find right parts?
