Default TH200-4R Speedo Driven Gear

I need a 33 tooth driven gear to compensate for my 3.42 rear axle.
Can anyone help me to locate this gear?
I've tried many places and sites.
I ordered one in stock from GM Parts Direct that they had, but was cancelled when it became unavailable (in 5 days).
If I find it, I'll share the location.

My approximate original setup
Rear axle gear ratio 2.72
Tire diameter in inches 26.40
Ratio Required 0.4817 (13 x 27 gear set => 13/27 = .4814)

My new setup
Rear axle gear ratio 3.42
Tire diameter in inches 27.40
Ratio Required 0.3976

The following are my Preferred Gear Combinations
Drive Driven Ratio (gear set)
10 25 0.4000
11 28 0.3929
12 20 0.4000
13 33 0.3939 (my original was a 13 x 27 set)
14 34 0.4000
15 38 0.3947
16 41 0.3902
17 43 0.3953
18 45 0.4000

I can therefore, utilize most any one of these gear combination.
The least costly would be the 33 driven gear, if I can find it.

Thanks,

I had a very hard time finding the gear I needed but found a seller on eBay that had an unadvertised one. The seller is samsstuff86. I had to go through eBay in order to contact the seller. He may be able to help. He was very easy to communicate with and the gear I bought from him was everything he told me.

Good luck
