Do you mean pictures 'or' instructions? Sorry, but you confused me for a bit...
Peak at these:
Sumner This one is a Camaro clip on a '48 GMC.
Frank This is a g-body clip on a '52 (I think) Chevy.
When clipping the most important difference between a Chevy and a GMC is the radiator mount. Sumner changed the whole setup and Frank shows how he recreated it.
