Alternator bracket pic request

If your pulley's line up and your problem is with the head hitting now that I looked at you picture . I would clearance the head to give it room.

But we have a machine shop.

If I did not have access to a mill here is what I would do

If you use a AC alternator with dual belt pulley and use a spacer to move the alternator front. Then use the rear belt V on the alternator You will move the alternator and won't have to move the rest of the pulley's front. The spacer I believe will be 1/8-3/16 longer Get another long front spacer and cut what you need. You will have plenty left to screw it up to make different lengths. Or just add a washer or two depending on the thickness of the washers. A dual pulley on a AC alternator the rear groove is closer to the alternator by 1/2 the groove.

I have Pulley's if you need one they rent the tool at autozone to pull them off. But you will need to split the alternator to press the pulley on so you are pushing on the shaft and not the housing. The draw back is you will have a empty front grove not being used . But I can turn one down and take the front off on the lathe. If you want a picture of the alternators compared I can send you one. Here is an AC alternator the same except for the pulley. And also a non AC.

I have them both here in the garage right now if you want measurments. I also have a bunch off if you want side by side pictures.

Don't think that you are going to machine the back off . You will reduce the Press fit. It will come off
Also you will need to cut the middle spacer to move the alternator front. What you cut off the middle spacer add the same length in front of the bracket behind the bolt . You can make all the spacers using one extra long spacer that I also have . Some one must have these parts near you. I am in North east PA.

Remember the dual grove pulley is closer to the alternator and lets you move it front.
Good luck . Steve
