dipstick tube

Hello again, I have a leaky 1983 C5 automatic transmission due to a crushed dipstick tube. All I can find on the web are replacements for the Ford C4 transmission. I believe that these two tranys share the same tube, but I can't find any info that says so? Can anyone shine some light on the...

is it press fitted or bolted to the inside of the oil pan? I've got one blocked and can't get the dipstick all the way down.. either pinched or the original tip is lodged in the end so I'm going to try replacing it. Help!
