I spent some time out in the garage today with the 73. I used it as a the guinea pig for the 75.

I did some measuring on the inside of the donor air cleaner base and although the outside height is the same as a shaker air cleaner base, the inside height is not the same. The donor base does not have the "drop base" to sit low on the carb so the shaker will sit too high on this base and hit the hood if I try to use it.

So it looks like I will need to find an actual shaker base either a repro 70-72 or a 73 to 79 and add the two mounting tabs I got from Norwood.

Oh well...anybody got a used shaker base from a 73 to 79 sitting around in the attic?

Just a reminder:
If you use Google Chrome, there is an add on that fixes the problem and displays the photos.

I found a baseplate, a nice rust free one from a Performance Years member. It was from a late 70's T/A. I carefully removed the snorkel and then glass-beaded the entire baseplate. Painted it with VHT satin black epoxy paint. I attached Norwood's shaker lid brackets to the outer rim with a couple of screws and nuts, after carefully measuring and marking with it should go. I also had to move the square breather element hole to clear the passenger side bracket which was in the exact same spot.

Here's how it came out. Now I need to find that pesky 70-75 steel shaker hood.

Nice.

Steve, what are the major differences in Trans Am hoods of the second generation? I would like to build a wanna-be 1970-1973 T/A.

The 70 to 76 hoods’ body lines are externally the same with minor underside bracing differences. 77 to 81 have a flatter body line to mate up with the 77 and newer urethane nose.

ahh, makes sense, Thank you for clarifying.

Look what I picked up today! Thanks to a tip by BentwheelBob (the guy who owns my old Black 72 Formula), I just got back from North Jersey with this. It was listed on Facebook -it's a 1975 hood that was already stripped and primered (top and bottom). It is in really nice shape and was only 45 minutes away. It was half the price of the new repro hood and no shipping costs! Yay!

Nice score, Steve!

Have you ever spoke to the Trans Am Reaper in the Chicago area? He specializes in early f body parts.
