I found some t-tops out of an 87 for $50 locally. He said they were the pin style tops and so is my 92. Is there anything different that wouldnt make them fit my 92?

 

Should fit just fine.

 

The older tops will have smaller pins than your 1992 tops - the 1992 tops have same size pin, but they are covered in plastic as I remember, making the ending result a larger pin - the older tops have just the metal pin, thus smaller. All that's required is to get the pin holes from the donor car if possible and swap them out - they simply bolt on. Or get them off any older car with the smaller pins (or ebay, thirdgenranch, hawks, etc).
