There are no replacement (side) emblems for the "Big Bolts",but the front hood emblems,(Available through "Classic trucks",Brothers","L.M.C".,and "Jim Carter",are the same for the pick-ups,as well as their bigger "Brothers". They're pricey,over $200.00,for T.F.hood emblem,(L.M.C.) I bought a pair of 6500 fender emblems,(from E-Bay),for about $75.00. A few pock marks,but much better than the originals! Looks like the emblems (in your pics), are from different years. Try soaking emblems over night in a 1-part white vinegar,2-parts water solution,making sure both emblems are completely submerged. Next day,use 00#,or finer steel wool,and gently scrub the surface,until rust and most pock marks come clean. The larger pock marks may require some more detail work,but the end result will surprise you. Not as good as new,but a little patina is expected on these vintage trucks,unless you're going for show quality. If you wish to have them re-finished,and re-plated,check the "links" section,under the "Services" heading. Beware: It's not cheap!!
