I am trying to find a rubber floor mat that will fit my 1988 pickup. The closest match I have found is the DEZ-DZ86501 (DeeZee rubber mat) for a 1989-1995 model. Since truck model years range from 84-88 and 89-95, I am wondering if this mat would be a suitable fit for my truck bed's internal dimensions. Does anyone have any advice on how I could get a mat that would fit my truck bed's internal dimensions? Would the DeeZee mat fit? Would the internal bed dimensions be close enough for a 1989-1995 mat to fit? Any assistance would be greatly appreciated. Thank you.
