Classic/Antique Car Repair: finding parts for my 79 ford ranchero, ford ranchero, hatch marks

Question
The tip of the transmission fluid dipstick broke off just above the hatch marks inside the dipstick tube! First, I'm paranoid to drive my car now! What suggestions for retrieval can you give me that I can attempt myself first?  Second, what specific information do I need to know to find a replacement dipstick? I was planning on going out to the 'the recyclers' on my own if need be.

Answer
Hi Abby:
The transmission filter will keep it from entering the gear box, so you are
safe to drive it to the shop to have the fluid and filter changed. Check with a
parts store if you need a new dip stick. Make sure you measure the total length
of the old stick+tip to ensure you get the right replacement.
