Guys I need some none IDI help
Well, guys ya'll are some of the most knowledgable group I know of, so here I go.
My grandfather has a 99 F150 4.2 5spd, and the tranny has gone to crap and he doesn't have the money to afford a new tranny. If I remember right its an M5OD correct?
Anyway, my 87 F150 has a new clutch and rebuilt T18 in it. So I am thinking about trying to swap it into his 99.
1. The bellhousing is the same
2. The M5OD has the internal slave cylinder. How do I hook up the external slave cylinder on my T18. Will the hydraulic line just swap?
3. Any other questions or suggestions to give me better idea?

The hydralic limne won't change over as far as i know because they are spld as a compleet unit master, slave and line. and come pre bled.
If you realy want to try you MAY be able to if you're LUCKY, knock out the roll in in the line at the slave and stuff it into the slave from the T18 that you were very carfule not to spill any fluid out of when you removed it. But this may or may not work.
Will the master off the 87 fit the 99? you may be able to swap the whole 87 set up.

When I did a diesel conversion on the ranger, I had to do some modding in the bell housing area for the slave cylinder for the diesel bell housing. In that case the hydraulic line was plastic.....thermoplastic, that is....my understanding is that plastic hydraulic lines have been the norm for ford stick shifts since they first came out.
What I did was cut the old fitting off the bottom of the line to disconnect the master cylinder and hydro line from the gasser type slave cylinder. Then to install the line on the fitting for the diesel slave cylinder, I gently heated up the line with a small butane torch only enough as needed to slide it on the fitting. As it cooled, it hardened and shrunk slightly to seal up again. Several years later and still no problems.
As long as both trucks use the plastic lines that are pressed over barb fittings, this trick should work. Otherwise, you could try and adapt the complete hydraulic clutch system from the donor truck.

This is def gonna be an interesting swap. I'm really worried about trying to adapt the crossmember, driveshaft, and whatever else comes to mind, but my grandfather doesn't have the ability to buy a new tranny, so I am just trying to get him by for a while.
Anyone know the length of an M5OD compared to a T18/19?

another question, why the heck is a clutch kit for a 99 $300 bucks for the CHEAP kit, but a LUK clutch for 87 I had only cost me 120?
I guess I'll figure out when I drop the tranny on the 99, but its making me worried about whats hiding in the bellhousing.

Cause you got a jap-job for a tranny, that's why - I absolutely hate that M5OD, totally unserviceable piece, and parts are way too overpriced. Seriously, I suspect it has to do with the concentric slave cylinder... David's trick may just work tho, I completely forgot the lines are plastic.

But a clutch kit for 95 302 with a M5OD, or a 92 351 ZF is only 160, what is special about the 99 to make it 300 to 400

I don't understand the logic behind the concentric slave cylinder. But I also don't inderstand the logic benind locating the timing train of an engine at the rear instead of the front either.
I never had to replace the slave cylinder in the ranger I mentioned earlier and truth be told, I got that perticular cylinder only because of a compatibility problem with the diesel swap. Theres no telling how many miles it already had on it or how long it sat in the wrecking yard before I pulled it off for my project. I really don't look forward to having to replace it should the time ever come though.
Tranny has to drop, and bell housing has to come off. Mitsubishi FM 146 in our case. Had to replace the 5th gear set TWICE so far.....
