Aurora AFX Slot Car Shell Clip (HO)
"This is a clip I needed to restore one of my AFX slot cars. The body shell is held onto the chassis via a small clip. Thankfully I had one from another car so copied it. The photos show the part I printed (in blue) next to the original. Hope it is helpful." - danricho
