79gooser Posted July 20, 2018 Report Share Posted July 20, 2018 I'm looking to put a new diff in my 79 KE30. I'm thinking about an 81 diff, (someone's got one and it's cheap). Would it even fit lengthwise, I know I'd need to weld on the leaf spring mounts and maybe modify my driveshaft, but otherwise would it fit in my car? I can do the mounts and such, I just want to make sure I won't have to do any major shortening of the axle. Any insight is greatly appreciated! -Goose Quote Link to comment Share on other sites More sharing options...
parrot Posted July 21, 2018 Report Share Posted July 21, 2018 What model code is the 81? Quote Link to comment Share on other sites More sharing options...
Jono.C Posted July 21, 2018 Report Share Posted July 21, 2018 Measure width of yours drum to drum and ask them to do the same? Easiest way to tell. The amount of diffs I’ve gone to look at that weren’t what they were advertised as also.. probably better to just get them to measure. There’s other considerations also though.. Handbrake cables, brake lines, brake Size ie will it be unbalanced on standard master and gear ratio etc If it’s just because yours isn’t in the best shape I’d just search for one same as yours or look into rebuilding it. Corolla centres can be swapped over between models for the most part but without knowing what diff you have now and what the “81” diff is it’s hard to comment Quote Link to comment Share on other sites More sharing options...
