There is large pre-amble to this post which will come with pictures when I can take and edit them - but for now...
I've got a toploader behind my little windsor (ratios unknown) going through to a Jag Rear.
As with the gearbox, I don't know what the final ratio is for the diff but I believe that it is pretty tall - 2.?? Apparently the engine is doing about c.1800rpm+ @ c.100kph (maybe up to 2000rpm - speedo has mysteriously died and so speed is from a nearby observer)
I imagine that to some degree the tall gearing will be overcome by the power/weight ratio (-thoughts anyone) however I guess I should investigate the lower ratios available and where (pref. S/E Melb) might I get:
-lower gear ratio sets
-LSD or locker (or whatever) packs
and finally some idea of price from those who've been down the road and is it worth the pain.
thankyou in anticipation
