A-body 727 dipstick tube

I have a 71 Dart with a 727 behind a 360LA. I need another dipstick tube for it that I can do the modification on as described in this thread:

727 dipstick tube boot style

Does anyone have a stock dipstick tube laying around that will work correctly with my car? It doesn't matter if it's dinged-up or deformed down by the O-ring since I will be cutting that part off.

Thanks
