The hole for the base pin is off set by about 1/8".
I previously ordered a similar grip for the birdshead wrangler and it fit great.  Wanted to match that grip on the full sized wrangler so I order this one from the same company.  It all appeared to be good until I tried to put the grips on.  The holes were misaligned by almost an 1/8".  I would have to re-drill the holes on both sides to make it fit.  I've sent off a request to return and exchange to see about getting a proper fitting one.
