[rexs73gto]

I've used the bearing in all of my engines since 1971. I tried the bushing in my 69 bird & it went out in just a bit over 1000 miles & I went to the bearing & didn't have to replace it & sold, traded it in on my 73 GTO & it still worked fine. At that time I ran the he!! out of the car on & off the track. I will use nothing but the bearing now. Also because the bearing is that much closer in tolerance you have to be correct on the install or you don't get the trans in. In that regards it also keeps the input shaft on the trans better in line.
