where can i pull the vacuum from for my booster if there is no provision in the back of my carb on my 69 camaro.i am doing a power disc conversion.

Use a pipe-thread fitting with a 3/8" nipple. It will thread into a hole already tapped into the intake, assuming your intake has a pre-tapped hole. Most intakes do, often right below the carb............. Use a little sealer around the threads, then tighten 'er up, and slide the booster hose onto the fitting.

The fitting will look something like this -

This one is a 90 degree, but they are available in straight as well.............

In the pic, see the brass plug in front of the dist. on the manifold behind the carb. If your manifold has that provision, you can put a fitting there for your booster vacuum.

Here you can see it with the fitting and hose connected.

BTW, I did a disc conversion on my '68 and it is fabulous! You'll love the disc brakes.
