I have two racing Toyota T50 gearboxes with custom dog engagement gears. 5-speed with 4th gear 1:1. They are stupidly expensive (about $4000 usd each used). Each gear can be changed. Right now they are set up as 5 speed overdrive close ratios. [5th can also be changed to a lower than 1st gear "pit gear"]

No bellhousings, but complete with shifter, tailhousing. These use the later mainshafts modified to run on roller bearings. Speedo has been blocked off.

To make an A-series bellhousing, we cut off an A-series front case, fill it with epoxy, and machine it flat. Then bolt it to the T50, still using the A-series throwout arm.
