Retroanaconda Posted September 29, 2010 Share Posted September 29, 2010 Disco 1 diffs are the same ratio as your 90's one, 3.54:1, unless of course yours is non-standard. The Disco diff may be 24-spline too (stronger), as that was around the changeover period I think. Quote Link to comment Share on other sites More sharing options...

Aragorn Posted September 29, 2010 Share Posted September 29, 2010 Its fine to use it, the gears are exactly the same. Given the prop bolted up its probably a 10 spline just like your old diff, as afaik 300series discos had the silly rotoflex thing. Quote Link to comment Share on other sites More sharing options...
