I have same camera (and 300 before) as back-up - love it - and I am 90% sure it should work, so only billing you $4.50 ($5.00 x 90%). Or, spend the $5.00 to buy the adapter ring and try it?
But curious why you find $5.00 unreasonable to have an out-of-production, non-approved for the camera, teleconvertor produced over a decade ago researched to get back a qualified, technical answer?
It's called good customer support and companies who provide it tend to keep their customers.
