Your right squatch, He's just lying about the disc conversion to sell it. The width of the grill and the parking brake handle are period correct for a 90 model trooper. The 87's and 88's have a solid parking brake handle.....the 90 and 91's had a handle that you had to pull-lock and twist to operate, kinda like a child saftey latch. The one in the picture has a large collar. its definitly a 90 or 91.squatch said:Very nice clean looking truck. However why would a '90 need to be converted from drums to discs. 10 bolt rears came with drums '87 back. "87 on 12 bolts had discs. Either the year is wrong or the rear axle has been swapped. HMMM! Price is right for sure. Little far away for me though.
