Chris,
Even the heat sink compound sold at remaining Radio Shack stores
should be fine or replacement on the new transistors. Most finals are
a pair of identical transistors or similar power rating at least. You
should replace both transistors even if you only find one bad one.
That is to ensure you have the same power gain in each.
In some cases, you might also need the driver transistor. Be sure and
check that it is not shorted. Usually the failures will be opens or
shorts.
Good Luck!

Here is an excellent youtube video on repairing a TenTec Eagle,
but the techniques can be used for a lot of other rigs.

I apologize if this has been pointed out before. I've done this
on several Corsair and Paragon transceivers in the past that
I picked up cheap at swapmeets and auctions. Even a TR7.
Hope this helps.
