The following are two mail messages that I saved. Not a GT6 but my guess is
the solution is similar.

Try Apple Hydraulics at 800-882-7753, I bought needles from them. Their
brochure says they also stock jets.

Fellow Scions,
Thanks to all who responded on my question of where to find the carb jets
for my '74 TR6. This people on this list are a great resource and I truly
appreciate everyone taking time to repond to my request.
I thought I'd summarize what I found out for the benefit of the list:
1. Turns out Apple Hydraulics does carry them. I talked to "Bob" (very
helpful and friendly) and the jets are $15.00 each.
2. Despite what may have been said by some suppliers, the pressed in jet
is replaceable. Apple Hydralics uses a brass honda valve guide (which Bob
offered to provide) to press the jets in and out. The soft brass prevents
damage to the jet.
Here's the procedure outlined by "Bob" from Apple:
1. Remove the carb fuel bowl, top cover damper cover and piston.
2. Using the valve guide, drive the jet downward toward the fuel bowl.
Note the position of the jet (ie, how deep is it inset from the carb
throat) before tapping the old jet out.
3. Insert the new jet from the bottom of the carb. Using the brass valve
guide, carefully tap the new jet into the same position as the old one.
