This is a 350. I bought a cheapy tab from the auto parts store and put it on. It seems like its a little farther away than it should be. The tabs we had at school seemed to hug the balancer. I dont know what size balancer is on it now cause we just bought the car. Ill have to check for receipts. Thanks for any info.

As long as you can line up the marks without parallax errors, you should be fine.
