I'd greatly appreciate it if someone could please post the distance between the bolt holes center to center on a 73 engine bar (not sure if it's the same for all years). I need the data to compare to the homemade one that was installed by the DAPO. This will help me to determine if the bar I have was created due to a fitment issue (body twist) or for some other reason that is beyond my imagination.

Thanks very much!!! Looks like about 41 5/8 from center to center. BTW, very clean looking engine...niiiccccee May I also ask, to unbolt the bar is there just a couple of washers and a nut on the top end of the big bolt? That's the way it was on my car. I had assumed it would be some system that wouldn't require counterholding given the position. Off to measure the homemade one....

The top of the bolt just has a nut and washers. You do have to counterhold it.

Rough measurement suggests that mine is 41 7/8, so 1/4" wider. If this is a true difference, is there any adjustment in the plates that hold the bolts, or would this be the reason for the homemade engine bar?

Thanks for additional info on the bolts and washer. Cn2800, if you could check the size of the bolt (length, diameter and threads), that would be great!

You might be able to find a used eng. bar for a 73 with a search in the classified forum. (IMG:style_emoticons/default/popcorn[1].gif)

I'm hoping to find one closer to home because shipping could be expensive. I'm a long way from needing it so lots of time to acquire one.

Make sure you get the correct style engine bar for your car, either late side shifter or early tail shifter, as they are not the same.

Interesting, I was vaguely aware that engine bars were not all the same, but didn't realize that the difference was due to the change from tailshift to sideshift.

Doug, This page may help. The engine bar on top is for side shift cars, with a hole through the bar for the shift linkage to pass, and the one on the bottom is for tail shift cars. Note the different engine mount arrangements for the different engine bars.
