Carburetor Question - Is this a good call?

Right? If Holley had the extra bolt holes like Edelbrock this thread wouldn't even exist.. However, what i'm thankful for is people here on the site helping me through and giving me some good info. I've learned a ton about adjustments i never knew before and honestly, i feel like i'm on the right path. But yah this is the stock 4 barrel intake on the Commando 273 engine.. id ditch the Holley before i ditch this!

I however no luck finding the bolts today at any of the auto parts stores that would carry them.. most parts stores around here don't even carry bolts.. odd. i'll dig the internets and see whats out there. I'll also call the company i got this plate from and see if they'll just exchange it out and that would solve everything, too.. the other plate had the right bolts it seems. @65Val - you don't happen to have a link to purchase the one pictured, do you?

But yes, i hope you're right there that once that vacuum issue is solved it'll just need some basic adjustments and off i go.
Sorry...I actually just grabbed that pic from the 'net, but back many moons ago, I used that same plate on the same intake you have, and, with the correct bolts, it worked just fine. Try a home center (Lowe's, etc.) for those bolts, or Fastenal/McMaster-Carr.
