Just a quick question after trying to find this all by myself. I have a 94 4.3 CPI. my question is what years did GM use this specific style of spider assembly? Trying to get my beast back on the road with a used unit, til I can make a more permanent repair. Thanks for any help on this silly little question.

 

What I do when I need to learn of the application of a part is find the GM part number at a GM parts online store and then compare that pn to those for Blazers for which I suspect it used the same.

RockAuto will show for what other applications a part can be used but it is not very detailed. However it will narrow the search.

 

Thanks for the tip. Turns out this part is unobtainable where I'm at. No parts stores can get it, no wrecking yards have it. Looks like I will have to send it to a rebuilder to get my blazer back on the road. Seriously, I have NEVER had so much trouble finding a part, which seems to me be a very common unit. Guess this is more of the "new normal".
