classic gearbox/diff help
 

how can you tell if have not matched the gearbox to your rear diff ?
how can i tell what my final drive is on my gearbox and what can i do to if they dont match ??

the gearbox will have a code starting either TY752 or TY754 depending on exact age (presuming its 5spd)

from the code you can ID the gearbox fitted and then work from there

just been out and checked both codes are the same on both gearboxes

6m-ty752vn4ba old
6m-ty752vn4ba new

so all should be good right ?
