Luggage rack installation dimensions ?

[Gunther]

Hi
I bought a used 69 chrome luggage rack and like to install it onto my 68 big block convertible.
Can somebody give me original installation dimensions, for example, how far back from the rear vent grills are the rack mounts ?
Thanks a lot
Gunther

I have the factory luggage rack holes on my 74's rear clip dont know if they were placed the same as yours but if you want the spacing let me know
