Sounds like you are determined to make the strut bar work. I know a good fab guy that could make you a spacer, you might also want to drill out the holes at the leading edge of the bar a little to get some slack. IMPORTANT item here about the bar, never try to remove bar when the car is off the ground ever!!! When the bar is mounted it's a stressed member of the body and you will end up stripping the threads in the front. Learned that the very hard and expensive way I'm going to take a "different" approach to the rear strut tower problem. I'd be so jelly if my long term plans for the engine bay prohibits using said bar. Best rear bar for the mr2 bar none.
Who do you plan on doing the paint work on your car. I recently got my hands on something that I plan on making look good before I make it fast. Ahh how things come around full circle and I care more about the look of things vs the speed of things now days, least for now. Some very special parts I've been waiting for have finally seen the light of day so I have to get them. I'll let the cat out the bag soon enough Eh two phase body builds fml.
I'll PM you my number hit me up and if I'm on the west Coast I'll swing over and turn a wrench. Been there done that hell I could name off all the sizes of the bolts on most any part it's that sad.
