Where to Buy 6-pack Metering Block?

[PurpleBeeper]

Where do I find a Holley metering block for a '70 4spd center carb? What about a '71 auto center carb? Are they the same?

May be a dumb question, but are these metering blocks the same as a 4bbl? If not, what are the differences if anyone knows.

On Chicago Carburetor's site, I see the following listings for metering blocks (both say "call" to see if they have one). What is the difference and which one(s) do I need for my '70 4spd and '71 auto carbs?

M1544 69-71 METERING BLOCK - Holley #4391, 4392
M1545 70-71 METERING BLOCK - Holley #4791, 4792

Thanks for the Help!

6-pak metering blocks aren't the same as regular 4bbl aftermarket. call the holley custom shop; they can get them.

What about A&A transmission?

Is it broken or just warped
Warped can be straitened

My '70 4spd center carb metering block is fine. The '71 auto carb is a parts carb that doesn't have a metering block and I'm thinking about just swapping them out so I can have the car running in an hour instead of several days while I rebuild the '70 carb.
