Donnie,
Do some research, but when I did my conversion, I replaced my Konis with new ones. However, I did see that Summit offered two lower priced items. There were the QA1 10 way adjustable struts for $229, HAL-H2001. There were also some from KYB that were dirt cheap. I don't know anything about them, but they had a Gas strut for $59, KYB-235009 or an adjustable ones for $89, KYB-743020. Put the part numbers into the Summit Racing website and see if that is what you are looking for.
Later
