Well, after some extensive searching I am going to answer my own post. I searched high and low for the various components to refurbish our old baffles and got prices anywhere from $40 to $5000 (from Hawker/Beech no less). And was told by one engine rebuilder in CA to check with SRS Aviation. I had used them once before for a elevator reskin and was really pleased with the work and shipping. But I did not know they were also in the business of replacement baffles. I talked to Dave, SRS Aviation as a source for the older style baffles (IO-470 and E225). I sent him some photos of the removed baffles and he set me up with replacements. I will know more this weekend after install if it is as great as it sounds. SRS baffles are PMA approved and are .050. thick. So no 337! All in all a better choice than trying to scab something together.
