Recently while researching gearbox upgrades to my surprise I found 2 companies in Australia who make straight cut gears in synchro and dog engagement versions.
http://www.allaboutgearboxes.com/
and http://www.ppgearbox.com.au/
I sent e-mails to both of them. first company did not reply, below is e-mail from PPG
We have only Dog engagement sets with billet forks designed. We did make a few last year and are only entertaining the idea of doing more early next year if production is working properly with our mainstream products. I suggest you get another 4 or 5 people interested who would buy sets and then we could maybe push for doing sets around christmas time.
They will be about $8000aud .
The ratio's are very close with a tall 1st gear and 1:1 fifth. The dog rings are replaceable and available as a spare part. You most likely wont need to replace anything if its a drag car with limited use througout the year.
Regards, Tim.
So, good news these parts exist, bad news - it costs $6050US plus shipping.
