Dual transfer-case

[NC854Runner]

I don't to much about dual transfer-case just what i've read. Just swap my tranny and transfer-case out of my 85 toyota 4Runner. Replaced the 85 5spd tranny and transfer-case with a 93 5spd tranny and transfer-case. I have the 85 transfer-case which is a top shift case, I wanted to know if this t-case can be used as my second t-case and if can how do i go about hooking the two up. If anyone would know i figured someone here would know.

what t-case is in the truck now top shift/forward shift 21 or 23 spline your old top shift case is a 21 spline so if your current case is 21 spline your good to go, you need to get marlins mco7,mco8 or mco8r10 in a 21 spline and there crossmember they come with directions but heres what you do in a nut shell which ever t-case matches up to your tranny is going to be your crawl box if your trans accepts top shift use a top shift for the front case if the trans accepts forward shift then use a forward shift, you tear down that t-case untell its just the reduction housing the front part then the adapter bolts to the back of that then a compleate top shift t-case bolts to the adapter the same way it would to the back of the tranny then the whole assembily bolts to the tranny

then  yes,  the forward shift  will be your front case,  then the adapter  on the back of the reduction box,  then the 85 tcase
