here is the other issue i am having. like i said i did a full conversion taking all the r32 mechanical parts and using it on the a31, the diff has also been changed to the lsd one that came with the r32. like others have stated the 1st half of the driveshaft is the same (with out the second half it would bolt sraight up as there is lots of room to pull it back to get the bolts to line up). the second half i needed to get adjusted so i got a machinist to cut and swap the end that bolts on to the first half. he said he maintained the same length and he balanced it. but when i bolted it up i needed to actually pull the center bracket back about 1/4 inch to line up the holes on the holes on the body of the car (not the whole drive shaft as i had little or no room room to move it. as you know the center bracket is made up of a rubber piece (not sure of the correct name) this is where the movement came from for me to get the bracket to move back 1/4 inch). now i have two questions linked to this. from this it looks like the 2nd half of the shaft is 1/4 inch to long or is this how it usually is? does anyone know the length of the second shaft from end to end. i am getting a slight vibration (not all the time) i don't know if he did not balance the shaft properly or if it has to do with the center bracket being pulled back 1/4 inch to get the holes lined up. would this cause any damage or the vibration. appreciate the help

I don't fully understand what you have done here, but I have done this conversion many times, never had any issues with the "hanger bearing" is the name your looking for, and it has always been a bolt up job, even with a R32 LSD

R32 front shaft onto the a31's rear shaft, early cefiro's need the flange swapped, easy once you have undone the big tight ass nut, not the case with series 2/3

once thats done there should be no issues with fitment,

take some pics for us, hopefully may be able to see whats up

if the shaft is vibrating, take it out of the g/box turn it 180 the slide it back in, had to do this with mine, problem went away

      Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed

      Looking for someone with a R34 front bar

      hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me

      Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
