You can see if Mitsubishi Parts Dept. have it available. They would be the only source. There # is 1800-553-7278.
It would be necessary to replace the tubes that had leaked. It would be advisable to replace all three CRT's due to age and there has been a pattern that if one leaked, the others will also.
Hope this helps,

How do i unhook the electrical connection from the display to the power wire?


You must watch the flexible cable or connector from display board vs Lower
Board or Main Motor Controller.
Then you must isolate the Main Motor Controller from Power Supply coming from coil or Transformer. +Pull out the fuse and turn Off.
See the block diagram that I did as people like you for yourself take carefully.

Mitsubishi VS-60705 red lamp replacement


The part you are describing is actually the red picture tube, not a lamp. The tube will come dry and you will need to disassemble the lens assembly on the old tube, drain the coolant (antifreeze), reassemble the parts and seal on the new picture tube, fill with fresh coolant, install the new tube, reconnect all wires including the dangerous high voltage lead, then realign the yoke and entire convergence circuits. This is not something that should be attempted by anyone without experience. If you try it yourself and the seal is not working perfectly, the coolant will drip down on your main boards and the set will be ruined. If you slip while lowering the new tube in the chassis there is a good chance you will crack the tube's neck, and that tube will be useless too.
