I'd bet people weren't rude, just told 'em like it is and he didn't like it. The truth hurts real bad these days it seems. But lets think this rationally, its some young kid with probably no fabrication skill, no knowledge of things that will screw him up like final driveline angles etc. how to set that LS in that body with the trans tailshaft in the right position etc.etc. how to fabricate the mount so the drive train sits correctly...things like this wills how up in the end and t would be a real head scratcher for the OP...
