gearbox question

[burgo]

i thought the diff between the f10 and f13 was that the f10 was a four speed and f13 was five but that appears to b rong so wot is the diff

[rgv_stu]

bellhousing is slightly larger on the f13 to accomadate a larger flywheel. internals are the same in both boxes and can be mixed/matched

[geordie_racer]

some f13's came as a close ratio box aswell

[Dan]

the internals are NOT the same, interchangable yes but not the same due to wide or close, 4speed or 5 speed etc etc

ok cheers lads
