In the mid 90's I really thought my vet brakes sucked. I was talking with my son and he said the ones on his GM dually one ton were fantastic, I looked at his unit and the next week I bought one from the wreckers for $20. NOt a clue how it would fit but I was determined to make it fit so out came all the stock braking system and in went the hydroboost. NO one told me it would fit, I had to guide lines but I was determined to make it work and the rest is history. I sold the idea to many corvette enthusists.
I hated the 400 turbo and 411 gears so I upgraded to the 700R and after blowing up 4 of them in one summer decided I really liked the mustang T5. Went out a picked one up, not a clue how to make it fit but by putting the mustang T5 on the bench right beside a blown and hard to come by chevy T5 the 1/2 inch adapter plate was born and again the rest is history.
Had to work out a clutch system? Just by luck I picked a 85 one ton hydraulic master cylinder as a donor and history again.

NONE of these swaps were suggested to me, no guidance whatever, never heard of a single one of these swaps and we all know how they turned out.
I can go on and on in other fields in the same way.
No I am capable of original thinking, I don't need a book to say what will work or not. sure I need guidance but in the end it will be my decision, not some book, not your experts, mine and mine alone and weather it works or not is my problem.
No stick your alignment or whatever where the sun never shines and leave me alone.

 

I got the ZF6 swap out of a book, same for the clamshell hood, the coil overs and double a arm front & rear suspension, the front steering end take off rack and pinion yadda yadda yadda....

As for the wether it works comment, if you advice others to do the same you have some responsibility in providing accurate information, or at least as accurate as can be. Closing your eyes for data proving it may not be the right way to do it is not only foolish it's not fair to those you are giving advice either. What if someone copied your system and it works? Excellent..but what if the result is massive vibration?

You re being very unreasonable, whenever a discussion goes against your way you get upset and what not. Something to think about for sure.

 

Small question from me,

I read this topic with great interest and the link Marck gave earlier.
Everywhere is stated that the engine and diff have to be parallel and offset in two planes. Why two?

Example:
If I leave the axle with a offset in two planes. When the UJ turns 360 degrees it would move "in/out" of alignment 4 times. When it moves the load is on more needles and if the alignment is correct you don't have any oscillations.

Now, if I were to align the horizontal plane but still have it parallel and offset in the vertical plane a UJ would still move around 2 times (miss-align and align) within 360 degrees turn and the oscillations are still canceled out by the opposing UJ.

What is the problem with the last option?

Greetings Peter.

 

1 plane would work, that's all you need. However in comes the engine offset and differential offset. Sice we have those and they are NOT equal you have to apply the common trick always used in the side view plane to the top view plane. How are you going to phase the driveshaft in the top view plane with these offsets not being equal without getting everything parallel? The reason is not the u joint, the 1 plane phasing is adequate to provide the needed movement, if it were just for that and there was either no engine/pinion offset or the engine and pinion offset were then same then it would be fine.

Also, the u joint never moves in and out of alignment, the alignment is always the same, the bearings just speed up and slow down depending on where they are in the misalignment angle.
