Hi folks.

My ke70s rear axle is getting pretty worn out, im considering using a ke30 axle, if it will fit, ke30 has leafs springs if i remember right? i also wonder if theres a gear ratio diffrence between them? i also have a carina rear axle i possible could use, but this is from a cariana diesel with a 1c engine so i have no idea what ratio.

The ke30 has a auto transmission not sure if its 2 speed or 3 speed, but the engine revs like hell when ur doing 100km/h down the highway, i been considering taking the engine and tranny and putting it into my ke70, but i would like to either get a rear diff with a lower gear ratio, or a newer tranny with 4 speed or something, any suggestions on how to do this cheap and easy? here the auto trannys are hard to come by and pretty much the only thing i know i can get a hold of is older trannys from for example a crown and i dont know if they are the same cept the bellhousing.

Thanks for any suggestions
