Propshaft flange holes distance for MNR reverse box
Hi all,
Working on the car (hoorah!) and just about to order the propshafts but wanted a sanity check from someone who has also fitted the MNR reverse box...
Could someone confirm that the flange holes come out to be 53mm and 44mm before I go and order my propshafts please?
And the Sierra diff are 59mm and 66mm?
Thanks,
Atif

Hi, measurements for small flange seem correct, it's a std 1140series flange 68.95mm (2.75" pcd with 40degree spacing.
Measurements for larger flange do not seem quite correct, I believe Sierra has 90mm pcd with 40degree spacing which should give 58.75mm & 68.94mm
between adjacent bolt holes.
All just theory based but might be worth double checking before ordering.
Cheers Davie

Thanks Davie. Yep, I measured diagonally and got 69mm for the reverse box and BEC prop adaptor. I got 90mm for the Sierra.
Now to order the propshaft!
