Advice sometimes depends on your location so good idea to put it in your profile.
North America, right? Not much Ta22 around I'm guessing.
As mentioned better off with a 81`or older 20 spline T50 from a TE7 corolla
or even better a pre 79? t50 from a Te3 or te5 corolla. Latter have shifters in correct position
Te7 boxes has the shifter 10 cm further back so bit of bodywork needed to fit.
Using 20 spline t50 saves you the cost of making a coustom driveshaft
You can use k40 crossmember along with t50 trns.mount to fit.
Id be looking for a te3 donor car for gearbox , pedalbox, hydroclutch setupp, engine crossmember,bigger brakes++
or 4ag it instead of 2t as you already have some of the driveline
Ae86 t50 are better but will either need a post 82 T bellh or some milling or lathe work done to a pre 82 bell
+ coustom driveshaft.
rwd 4age gearboxes and bells are worth a fair bit more than 2T stuff on most markets, don't know about north America tho
All about supply and demand I recon
