Hi guys,I hope someone can answer these questions for me,I can't seem to find anyone who can.I have a 1986 1500 Sierra GMC Pickup truck,I would like to change it to a Sierra Granda inside and out,I would like to get a new seat,front bumper,dash cover and floor mats for it,Does anyone know where I can go to get these,I am also having problems with the gas mileage,I only get 12 miles to a gallon with it right now,Can I put an overdrive R-4 Transin in it to get better gas mileage? I have a 305-3speed in it already it is all original.
