Cab mounts 386

Hello I was working on changing my cab mounts today. When I went to do the one on the driver's side it had a 1 in. Thick spacer welded on the mounting bracket. The passenger side did not have the spacer. I looked at a diagram and it shows the spacer on the bracket and on the passenger side it looks like there's a broken weld from a space being on there previously. So I assumed there was supposed to be one on there and made one for it... when I went to put the cab mounts in on the driver side the bolt is not long enough... so now I'm confused whether the spacers are supposed to be in there or not? Any harm done in just cutting the one off the driver side and running no spacers so my bolts are long enough? Any help is appreciated!!!
