On some models of general motors starter shims are required to maintain
the recommended clearance between the starter and flywheel.
If not, then the starter will hang on the flywheel after motor is started and
damage it (The teeth are bottoming out when this occurs). They sell starter shims at
the auto parts store.
Hope this helps.

I have a 97 GMC 350 vortec that the starter motor kicks back. Its been at the locl shop know for a week Figured I'd research it a little

what exactly do you mean by "kicks back"
IN all engines if the engine fires hard against the rotation of the starter motor, it indicates that the ignition timing is way too far advanced
GM products are around the 10 -12 DEgrees BTDC static timing and any thing over that will cause problems
If the timing is right then I would be considering replacing the crank position sensor and/or the ignition control module

What is the bar the bolts to the block and then to the back of the starter and stops the starter from torqueing. its an 85 k5 blazer high output 350 v8

The bar is simply a brace. On one that old, it may be difficult to get from a dealer but you may find one in a scrapyard. Problem is that to save time, many techs used to leave it off when changing the starter...Most will work without it but if the engine kicks back due to a bit of moisture in the distributor cap or any other item that can cause a cross-fire, if it's not in place the starter nose will break.
If you can't find one you could actually make one using a piece of steel Any support there is better than none at all..

The high pressure and low pressure hoses are different sizes at the gear box. And the low pressure /return hose is usually rubber with a clamp at the back off the pump.
