Ah, but you are going to miss all the fun of stripping/rebuilding the range box to redrill the front of the case

If you haven't seen it, NW Fab has a manual on the basic process you will need to follow at http://www.northwestfab.com/203-205adaptorinstall.html

I have some sort of np203 gearbox floating around here, i'll try to dig it out from under the bench and check it out. If its a 32 spline, i'll let you know Nick, I have no use for it at this time. I'll probably go Klune if I decide I need more gear.

crossmembers

moving forward on this doubler. what would everybody do for the crossmember to support the 203 and 205? could u reuse the 203 or 205 doubler, drill and cut it to mount to the frame and go on with life or whip out some round or square tubing and fab one up? do you need two crossmembers one for each tcase?

I think there is a good crossmember thread on here to search up in this part of the forum, can't remember if it covered doublers or not. I was gonna try and just fit two OEM crossmembers... but have no idea if that'll work. Maybe you can skip the crossmember under the tranny to 203 and just move it to locate under the adaptor foot between the range box and 205.


Brad, if the adaptor is still bolted to the front of that GM203 and it only has 4 bolt holes for the transmission it will be 27 spline, if there are 6 bolt holes for the tranny it's gonna be the 32 spline.

Maybe someone else here has a small bearing or small bearing case they can get a meaurement off of, I only have the large case. Are you just trying to figure how much to have the case bored up to fit a large bearing?

No, I think I can get a bearing that will let you put a big bearing input shaft (like a T-400 or ford) into a small bearing case thereby eliminating the machine work. Dennis

I'd look around or post here in the wanted section for a 176 bell, I got ming for ~$45 but if you are in a hurry you can buy one new from www.4wd.com for ~$200.

yeah im def not in a 200 dollar hurry, i can wait.

once i get the bellhousing, what clutch do i get? i was reading some stuff from OC and i think scotty about using a clutch meant for a hydraulic slave cylinder with a clutch design for a straight linkage setup being different. mines gonna stay with the linkage so im not real sure what to get. i thought i seen it somewhere people using a clutch out of a mustang.

If you use stock Jeep clutch components all you need is a Ford disc and an adapted input bushing for the crank available at Advance Adaptors. I can't advise you on hydraulic bits, but if you anticipate a lot of frame flex you might want to go that route. I've done just about as much shifting without using a clutch pedal as I have with one so in the rare case my linkage might bind up I'm not going to worry about it personally... but that's just my feeling about it and it might change if my butt was hanging off a cliff

I believe a disk from an early 80s 5.0L mustang with T-5 should have the disk you want. You're looking for an 11" (10.5" if you can't find an 11") disk with a 10 spline 1 1/8 (I think) input.
