Looking for experienced opinions on removing k-member.

Did this very thing on a 68 Dart. With proper planning it isn't too bad. I'm 79 and it took me 6 days to complete. I drew everything out got all the parts needed jacked up the car on a Saturday and drove it out of the garage on Friday afternoon. BUT it was a lot of long days and not a whole lot of fun but it was well worth the effort.
