It's in a '69 Charger. I found that the linkage would need almost a 3/4" carb spacer to clear the intake in the choke area, which causes me hood clearance concerns with the stock unsilenced air cleaner. Any ideas for modifications that will buy me some clearance? I'm not crazy about grinding the intake if I can avoid it. Thanks for your input and ideas! MOPARS ONLY!

Drop base air cleaner base , Ford motorsport sells a 13" air cleaner that fit the holley prefectly and uses the same size airfilter as your factory unsilenced unit . You pretty much have it figured out , the intake is the issue in the choke area , in 1970 the choke design was changed and it allows a holley to be bolted on without any mods to the intake .

First for the linkage to clear you need about a 3/8ths spacer, they use to be pretty easy to find but I haven't seen one in years...But 1/2" ones are avalible....Also if your running a stock intake you should have more room than you seem to think.. Try losely wadding up a few balls of tin foil & place them around your aircleaner & shut your hood, that will give you an accurate idea of how much room you really have... BTW you'll need a holley/mopar throttle adapter...

It will make every thing clear and give you a few more HP Plus it will keep the carb off the HOT intake. You can also mount your fuel line backwards so it won't dump right into the distrib.

Moroso and others make them, Yes Moroso and other make a drop base but the FORD MOTORSPORT unit is the ONLY one uses the same filter that fits the stock unsilenced air cleaner . Moroso and others use a 14" filter element

I started out trying the Mr. Gasket #97 heat dissipators that add up to 1/4", but they just aren't tall enough to clear the '69 intake. John, you have a PM. MOPARS ONLY!
