I have a 95 S10 4x4 that I am in the process of replacing the control arms on one side for the second time. The replacements don't seem right. The originals that I took off had been cut and welded. The lower was shorter and top was longer. Ordered replacements through Napa Auto parts. I attached a pictures of anyone can provide maybe a solution the keys are maxed out.

 

I stopped buying garbage from NAPA 30 Years ago.
That tow hook on the front is scary, thats not a tow vehicle, might be a offroad recovery hook? Id check for frame damage.

Search Google for GM NOS parts, several Dealers still have nos stuff.

I have a new set of GM NOS upper arms for a 95 S10 if you want them. I bought them before realizing some chucklehead hadnt locked the bolts down....

 

Is it possible you have purchased or received a lower control arm that's designed for a ZR2? Those are longer than the LCA for the non-ZR2 trucks, and are a different part number. If the part you received is for a truck equipped with the "highrider" or "higher-wider" package then it's designed for a ZR2.

FYI, the upper control arms are the same for the ZR2 and non-ZR2 trucks. The ZR2 get's it's additional width due to a change in the UCA mounting locations on the frame.

 

In the future please be more specific in your subject line. Like, " Please help with control arm."
