  2. 6 rib is the newer 091 gearbox fitted from model year 76 to 1.6l & 2.ol engines and T25's, reverse light switch on the side, up till then it was the 002 gearbox reverse light switch on the end.
     
  3. My CE three-ribber has the reverse switch on the side ;)

    The only box I ever had with the switch on the end was 1968 3 rib.
     
  5. Actually they might have changed on the crossovers

    1700 type-4 + it's original 3-rib box is a great combo, but requires thrashing up the revs to where the power is. I loved mine. The stock exhaust system also seems more balanced with it than the bigger engines are but that's just impression, I have no proof.
     
  7. Can anyone Id this gearbox for me? found it in my Dad's garage when clearing out - think it might be a T25? Could be a synchro? Cheers

    Yes I think synchro.
     
  10. That's a syncro front diff, @theBusmonkey may well be interested in it

  13. Here's the other one I have - possibly also a T25 synchro? Poor phots I know but it is up on a shelf and I can't get it down on my own!

  16. Its a front grille from a T25?
     
  17. all i can say is that its a diesel bellhousing so probably a diesel box, would need to see a picture of the other end of it to see if it is a syncro box, but if its with that front diff then it is very possible
