As part of trying to get the height of the shaker base down far enough to clear the hood, I was told a while back that Accel makes a throttle body that is about 1/4" shorter than the unit which I have. While I wasn't excited about shelling out the $$$ for another TB when I have a perfectly workable one, I needed the 1/4". Especially after moving up to the 2.5" height shaker base.
Then the problem became finding one. I called Accel directly, and they are out of stock for 3 - 4 weeks! They gave me a couple of dealer names, but they also were out. Then I randomly decided to check on Amazon. Sure enough, one was listed as in-stock. I emailed the vendor, and he said they have one. So I ordered it.
It arrived, and I was all excited, until Eric informed me that the IAC plastic housing was broken. The box had been dropped, apparently right onto the IAC, and it shattered the plastic. It wasn't usable. Sigh...
So I called Accel to ask about a possible replacement, and the tech support guy (who acted like he could care less about helping me) gave me a part # for the replacement. When I looked it up on Summit, it's a completely different style of part.
It's a screw in unit, and this one attaches with 2 screws. Great...
Eric then went hunting, and he somehow found one that matched based on a picture found on Google! Isn't the internet awesome?! It was listed as a Mercruiser part, and was pretty pricey. So in parallel, I contacted the seller of the TB. Turns out this was the only one they had in stock, so they too were out for 3 - 4 weeks. Ugh!
Long story shorter, Eric found the IAC was also used in several GM applications, and sure enough, the local O'Reilly's AutoParts store had one in stock! $65 later, we had a replacement to solve this problem.
This was a lot of trouble to go through to save 1/4" in shaker height! We have worked HARD to have a functional shaker on this car!!!
