and further to fj25/28 value there are many components that are unique to that model that often go astray. original rims are a big one. also both master cylinders. early horns are different also. and the front bumper, diffs, brake assemblies....etc. im still learning all this. usually a later component can be easily made to fit but it all depends on your definition of unmolested. the factory tool rolls are very collectable and a big bonus. fj25 jack is unique for the obsessed.
any old car i source now i ask the previous owner if they have any old photos of the vehicle that i would be able to copy. my 25 owner didnt have photos unfortunately but he typed me a page of anecdotes, when where he bought it, how he used it, coupla stories, and photocopy of his original reciept etc. these touches add to the value for me. any vehicles we enthusiests preserve now will outlive all of us and its nice to keep their stories intact.
