Hello again, welcome to my newest prob: I need a few hood measurements to compare with. For 73-80 hood, across the rear from side to side, measured right in the center of the louvers. I get 69 13/16. I have a wide gap only on one side with doors fitted and fenders fitted to door with a very good, consistent gap. The hood is new from Holley, I bought it about 3-4 years ago. Hood had a nice gap all the way around except the wide gap at rear on one side. My cab and rad support is still loose so I can scoot around but nothing works since the fenders are adjusted in and there just not enough hood. Maybe a bad stamping since it's aftermarket. I would have went with AMD but at the time Holley I believe was the only source for a hood with the smooth 73-78 front. Please don't anyone scratch paint for my sake, maybe measure an old hood that did fit good. Thanks.

I have all new cab/rad support bushing, all loose. I just learned of the hole next to the cab bushings for a pry bar and played with moving the cab and rad support around and got the gap a lot better but still about .150 wider than the other side. I'll play with scooting everything around some more but would still like to know what other hoods measure. Thanks.

Hood width doesn't effect the gap on just one side. It's just that more time needs spent with adjustments.

Also, your .150 difference is well within factory tolerances of the era.

Thanks for the reply, Yes I know they were sloppy. I was just thinking that maybe the hood was stamped short on one side being it's aftermarket. I'm still working on it. I'll post up some pics when I get it as good as I can.

That's way tighter than we built them.

I would have said our fixture was about a quarter inch.

I watched my guys put on about 1.8 million fenders (900,000 trucks x 2 per truck) with that setup.
