Restoring a classic GM A-body? This manual steering pitman arm is exactly what you need for 1964-1967 models like Chevelle, GTO, Skylark, and other midsize GM cars! Made by Johnny Law Motors (MPN JLM925A3), this is a brand new part with gloss black powder coating that looks fantastic. It's 6.5" overall with 5" center-to-center, featuring a 1 1/16" spline diameter with 32 splines (4 master splines). The tapered stud end goes from 9/16" to 5/8". This is an OE replacement that meets or exceeds OEM standards - not some cheap knockoff. Includes USA-based technical support if you need help. It's designed for manual steering gearboxes (not power steering). Pitman arms are wear items that can get sloppy over time, affecting your steering precision. If you're doing a restoration or just need to tighten up the steering on your classic GM, this quality pitman arm will make a noticeable difference. Get that crisp, direct steering feel back in your vintage ride!
