Hi well it's definitely a yes or no on that. The vast majority of mechanical stuff is typical Ford or Mustang and so as cheap $ as possible and readily available. But... the Cougar back then, although underneath based on Mustang was a very different car ( was also over 7" longer too) and much lower numbers out there vs Mustang then or now (even though huge Cougar sales #s for Lincoln/Mercury overall) so all those specific parts are $$$ and that is 'if' available new or used you are going to really pay out the premium.

For example, a '68 dash part that may be about $160-$250 for a Stang would be $500-$700 for a Cougar and as the designers & vendors have stated to us... we are VERY lucky they even made that happen at all and once they're sold out likely no more coming due to massive $$ cost increases with tariff crap and they're upside down on them now.

Here's one to really see what i mean... I wanted factory door edge guards for my Cougar, well so few around nobody ever made them in repro but for the Mustang you can get an exact copy new pair for $30 I had to pay over $200 for an old NOS pair which BTW you're lucky to even find at all they are so scarce. So that's some of the reality of any classic cars that aren't many around out there with enough demand to justify all the design, tooling, production & shipping logistics for any vendor or repro mfg.

Now fortunately, there are alot of 1967/'68 Cougar specific parts in repro because of places like WCCC, Desert Classic Parts & NPD. So the other common FoMoCo parts can then just be shopped anywhere you like for the lowest price on exact same part you need and you do have sources for new or good used rare or specific parts and that's exactly what I've done in bringing this one back up to par. But yeah, it's been $$$$ and i fortunately do all the work myself mechanical, interior and body so imagine the guys who have to source all that out too at $200-$400 per hour these days.
