Even better 'squirt the '68 and save some fuel.. What I did was convert the fuel tank to have both carb and an intank EFI pump. Then ran the fuel lines up to the engine. Once I had the wiring harness installed and tested with my ohm meter (point to point and ground celarance check) I yanked the carb,mechanical fuel pump and pluged the mechanical fuel pump inlet line. Once that ws done I installed the TBI (having pre-fit the linkage previously) and fired it up.
This was if you run into an issue that can't be resolved you can revert back in 1/2 hour.
