My 1972 F7 Dart Swinger

My speedometer is pretty inaccurate because I’ve changed transmissions, rear axle and tire size. I’ve seen mention of long and short speedometer gear shafts but I don’t know what each style measures.

I took mine out today to see what I’ve got. It measures around 4.5”. So, is this a long shaft or short?

I installed the jack and hardware brackets in the trunk and I put the front spoiler on today too! Love the way it looks
