This site may help. It lists the PCD (or bolt pattern) for Vettes:

Problem is going to be wheel offset / backspacing differences; very big on C4 rims ( 6"+ ).
By the time you space the rim out to clear suspension may be too far outside guard
PM me if you want to borrow a C4 rim to test fit

thanks mate, i do also have a c4 with 18" wheels, and i was told the offset is very big on that, but my main issue is that i was told that the stud
pattern varies, so i was going to get 2" spacers that fit a c3 then the other end will be a c4/holden/bmw pattern, then i have a much greater choice
when picking the wheels for the c3. so from what you know, you think c3 and c4 stud patterns are the same?? i can see a very deep dish on the c3
standard wheels, i'm sure not many other wheels will fit, but then by doing this i might have a lot more options. Thanks again.

FYI, BMW bolt pattern is 120mm and Corvettes have 120.65mm (4.75")
I would NOT bolt 5x120mm pattern wheels without adaptors on a Corvette!
All 1968s carry the stigma of being "the worse quality" of all Corvettes.

Stud pattern is the same
From what I am seeing online C3's ( 78 at least ) had 4" backspacing
So a 2" spacer would let you run a 6" backspacing rim
Biggest problem with aftermarket wheels appears to be caliper clearance; not susp clearance
