FULL_MEDIC,

if you got them from RF parts, then they are the real deal.
90 bucks! ouch!

Remember that the emitter and collector on your MRF497's are switched around from the way they are on the stock finals. (2SC2312's)
you will need to bend those two pins in order to accommodate the new pinout.
be sure to put some heat shrink tubing on the middle lead to prevent any accidental shorting.

you will also need to re-set the bias after your parts change.
