Well after some digging and looking and some advice from the fb group, looks like 3/8 and 7/16 with a 16 pitch but after further inspection i beleive the wrong bracket may be on my truck. Took some picks as it sits one hole does not line up with the block hole and i am missing several, good thing is i somehow have one 3/8 short bolt from something that will fit one of the short holes. I can get the extra long bolts off ebay..
Best thing is to take this thing apart compressor off and start there.. oh the stuff we get into with these old beasts but gotta love'em.
These are the power steering and A/C bracket bolts
Finally able to get the A/C compressor off and look at the brackets better, im pretty sure this bracket does not go on this 7.3.
I have one bolt hole in the bracket that does not line up with the hole in the block.. i took more pics.
Does anyone know if 6.9 brackets are different or i may be off a gasser.. i just know it sure as heck does not fit correctly....
Not zure on the pics if u can tell or not, a tight spot to get a pic at..
Thanks everyone..
