Stepdown engine vent toob

Lee ODell

I have 4 extra engine vent toobs trying to get the right one for my 52 Hornet with automatic trans. I looked in the parts book and to my surprise there are 9 different part numbers for the stepdown. However, I can not find any part numbers on them to ID them. Can someone tell how to ID one at a swap meet?

What a hassel to write this. Every time I start a new line the screen jumps somewhere else and I have to find it again to add one more line of information on the next line and it jumps one or two more times before I can write the next line. It's taken a half hour to write this.

I hope they get this new forum fixed soon.
