HUGE Lot – Vintage 60s/70s Mattel Red Line Hot Wheels Sizzlers Track Set Pieces. Most of this lot was mine when I was a kid – all of the red line pieces for sure. I added the other pieces for my kids to play with. Below is my description of what most of this includes. 60 – 2′ Red Line pieces of track. 42 – other track pieces (plus a few others on the loops). 42 – Red Line purple track joiners. 17 – other track joiners (plus a few others on the loops). 3 – Red Line full curves. 5 – other 180 full curves. 2 – Red Line half curves. 2 – Red Line loops. 5 – other loops (some with track currently attached). 2 – rod runners (1 single & 1 double). 3 mounting clamps, 5 starting blocks, 1 checkered flag finish line, and some other pieces.
