KSC
As a matter of fact Yes, two come to mind and both were addressed. First was tuning the motor with fresh plugs the number 8 plug is impossible to reach and way too close to the firewall. Solution, was cut a trap door in the firewall get the plug from inside the footwell carpet hides it.The other was clutch adjustment down on bell housing (our has a cable) another little trap door and a special wrench was made to make that chore a pleasure.
Honestly as I was putting car together tried to think ahead enough to not have to pull the body off. Even with all that knew it was important to spend the time to drill and tap all body mount positions.
