Do the coily transfer case flanges fit the older gear driven cases ???????? I'm fitting gear driven case to coily and don't know if I need to find a large flange case or just fit my coily flanges to any 1.3 case

My 88 had different flanges to a 91 so I guess the question is what model is the gear driven case you have out of??

He hasnt picked one up yet but what he needs to know is if he gets one with the wrong flanges can he take the flanges off the coily transfer and put them on the gear driven one.

I guess so but I went the other way and used the right shafts to suit, but I guess he would then be buying xfer+jack shaft+ F&R drive shafts

yes the coily flanges do fit the 1.3 gear driven t-case.....you must also get rid of the coily t-case mounts and use the mounts of the gear driven t-case....

Yep you will need the 1.3 gear diven case ......all mountin hardware (beef up mount points on drivers side mount aswell as chassis mount......and get rid of the passenger side single bush <these tear in half>.... And run a standard zook body mount bush with a high tensile bolt and solid mount it) In my coily i also ran the gear driven jack shaft (shaft from gearbox to transfer) the coily ones are tiny as and i aslo think there could be a size diiference.........

Thanks guys . So the flanges on all 1.3 cases large ,small , coily are interchangable .

NO they DONT fit , not unless you make up 8mm spacers to take up the extra spline sticking out , and fit different seals to the case with .5mm smaller ID, and the rear output flange would need to be machined .

Hey

Even though the coilly flanges are threaded (easier to work on) the leafy flanges are a better flanger for their box

Why I hear you say? I am glad you asked! ( I love the curiosity show )

The leafy flanges have a shroud on the back of them protecting the seal from mud, sticks etc..... Just use them and buy a bunch a bolts to fit.

Yea thats what I did , But I asked the question before I found my new case, as the early model cases have small flanges that dont match the coily flanges, and I wanted to know if I could take the flanges off the coily case & fit them to the gear driven case if I got the old case with small flanges . Lucky I found a 90 model case with the large flanges , but curiosity got the better of me so I pulled a flange off the coily case to see if they interchange and as I suspected they dont, same spline but different length , 8mm shorter & .5 mm smaller seal dia, and all 3 coily flanges appear to be the same, where the gear case has a different flange on the rear output that dosen't run in the seal.
