To swap ke70 extension housing onto ke55 or vice versa is it just a straight swap of housings and it will shift fine or will there need to be adjustments to any linkages inside ?

straight swap but need the shifter that goes with the housing

Plus the shifter location will change.

Thanks, I have the shifter and am aware the location changes.

Have a 55 box that i want to put the 70 housing on as my 20 is already set for 70 box plus i like the 70 location more.

So i may have a 55 extension housing and shifter for sale soon...
