'78-96' Impala/Caprice 2'' pin same as STD small metric .The metric is 1 1/4 shorter over all (pin to top is shorter) . Think the s-10 and small metric are the same . '78-96' Impala/Caprice will make for a wider front end by 7/8'' vs the small metric.I was selling a spindle that looked like a Impala but was a cast steel part that GM was making and the Impalas that I got out of the junk yard where cast iron .
