1974 Barracuda headliner

I recently swapped a roof onto a 1974 Barracuda. The entire roof was done inner and outer panels. The replacement roof came off of a 1970 Barracuda. I did not realize at the time that the 74 roof uses 4 bows and the 70 uses 5 for the headliner. I would like to stay with the 4 bow headliner. Can anyone here give me the measurements for where the bow retainer clips go on a 4 bow roof ( of coarse I don't have the original roof that would makes things too easy ). Any help would be great. Thanks.
