found a 3rd row bench seat from a 2000-2006 suburban/yukon XL/denali XL. ebay ad says it does NOT fit regular yukon/denali/escalade/etc. does anybody know if that means its too big for '53 3100? i've asked seller for measurements and gotten no response. i keep reading that '88+ truck seats will work, but the "XL" on this one makes me think it might be too big?
