75-76 t/t?????????
The differences: Hood: 75 has center headlight grill & reflective stickers, 76 had offset headlight & open grill, non-reflective stickers. 75 had Salsbury secondary, 76 was Arctic (I think jackshafts were also different). 75 used sno-twister belly-pan, without crankcase cooling duct, 76 was unique bellypan. Engine was nearly identical on both years. Gearing may have been different by a tooth or 2 on top sprocket...don't recall, suspension may have been a little different too, but not that much.
