Will an EV-81 tube fit in a Border Patrol DAC?

Hello, I would like to replace the stock EZ80 rectifier

with an EZ81 rectifier in a Border Patrol DAC but don’t

know how to. There doesn’t appear to be enough room

in the tube chassis to do so, since the 81 tube is 3/4 inch

longer than the 80

Any help would be greatly appreciated.
thank you!
