I would like to start restoring my 68 rag top and would like to know do alot of the 67 parts fit. Also, because I have discs on the front would I require 15x7 wheels. Any help is greatly appreciated!!!

In general most parts should work, however the look/finish of some parts are different by year. Easiest way to check would be to look at the parts catalogs, Ames, Performance Years, Year One etc. There are subtle differences between 67 & 68, more diff with '69.
