Kitchen Cabinet Shelf Clip

I am trying to replace plastic shelf clips that were installed with my kitchen cabinets approximately 15 years ago or more. The markings on the bracket are as follows:

P.X. IND. 34

PATENTED

W.HANOVER, MA.

I think the peg which is inserted into the existing cabinet hole measures 1/4" in circumfrence and 1/4" in depth. I have purchased a similar product in local hardware stores at the same size, but they cannot be inserted completely into the opening. If necessary, I could take a picture and send it but I'm sure you probably know exactly what a need. The verticle measurement of the clip is approximately 2 1/4" or so. I would so appreciate hearing from you regarding this part. Thanks in advance.

Tom - Hope I transmitted these photos properly (my children are embarrassed at my lack of "TECHNO" skills....oh, well....hope this helps. Let me know if you need more. Thanks.

I also need these but my shelf is 3/4 inch, not 1/2 inch. Do you have these?
