I’ve found only a single reference to impala control arm used on an OBS. A little research shows they are 3/4” narrower than stock. Has anyone made this swap or can share some info?
Project: 94 Sierra RCSB, LS364/450, TKO-600, bell tech 3/5
GMT400 TILT W/O shifter levers are getting damn expensive, so, I grabbed a 91 Camaro, replaced firewall flange from the Sierra and installed a new windshield washer switch....less than $100
94 RCSB .... is there a different cross member for auto or manual? I’ve converted from auto to manual with an LS / TKO-600 combo and can’t get firewall clearance, current crossmember is all the way forward .
