With my gibson shaft chasing same vibrations, new engine & gearbox mounts, spacers under the centre bearing, replacing diff bush's, back to gibsons, took it to hardy spicer and it turned out to be 'bent' Another $400 to them but at least it's fixed (%90 because of IMS hat)

This is common with aftermarket tail shafts. Well it was a few years back. Generally the uni joints vibrate more than the CV joint on the factory shaft. The new shaft you have also does not have the factory doughnut damper/bush so it will transfer more noise and vibration. Depending on the height of the ute you may have to add some spacers to lower the center bearing and align the shaft to have less angle between the uni joints.

Hey @Joska_unofficial Barra into sierra sounds pretty tough. Lots of good info on this site, have a bit of a read through these sections; https://www.fordxr6turbo.com/forum/forum/231-conversions-transplants-and-frankensteins/ https://www.fordxr6turbo.com/forum/forum/123-300-club/ https://www.fordxr6turbo.com/forum/forum/152-400-club/ And this thread Late 2008 onwards (FG & FG-X models) turbo motors will handle your power goal with ease with some valve springs, oil pump gears are good insurance. Otherwise you can go the N/A + built option of course. Injector Dynamics have a reputation for being the best for this application, Bosch 1000s will do the job though. Turbos - the factory GT3540 with modified turbine housing (enlarged port & flap on internal wastegate) has worked well for a lot of people, mine with billet compressor wheel makes a bit over 400rwkw on 98 and just under 440rwkw on e85. Since your best option is probably buying parts in from the US, I'd be going the gtx3576 gen 2. If you could make the standard intake & exhaust manifolds work you've be laughing, but as you've said not likely. An aftermarket plenum like Plazmaman's retro conversion is something to consider; definitely not cheap but they've been especially designed to suit engine swaps for old Falcons, Capris, Cortinas etc so could save you a lot of pain. Hit them up with an email. https://plazmaman.com/product/billet-ba-bf-fg-retro-conversion-manifold/ RE actual motors, there are a couple of guys on here from the US - Florida I think - one of them has imported 5 or so N/A barras for these sort of conversions. May be worth a look considering your location? @Mustangman570 & @SelectivePC All the best man, look forward to this build PS. Your English is expert level compared to some of the tards that jump on here from time to time...

changed them over yesterday- TPMS went across to the aftermarket rims no probs. ride feels no difference- probably due to the airbag suspension being so good. very happy with the result.

Last week I ordered a new tail shaft from GJ Drivelines. It's a Pro Series - $1890 for anyone curious. Super simple to fit up - really nice looking bit of gear. After fitting, it felt good to drive around. I noticed under acceleration for 50+ I'd get some not so great vibrations. I'd noticed lately that jamming it in lower gears the gear stick would move a considerable amount (with engine torque). Turns out my gearbox mounts were shagged. I was able to replace them for $50 and only took me 20mins to do! Thinking this solved my issues, I took another test drive. No luck. I'd noticed a clunk developed in the front end over the past week as well after driving on some rough roads the weekend prior, I put it down to a flogged out bush. After having a hunch and checking the engine mounts, I'd discovered I had a missing mount nut 😕 Still trying to source something that fits.

Couldn't get to the thread to repair it, The B Series where much easier supposedly. Even with the mount out or the engine jacked all the way up still couldnt get to it. Now reckons the cross member has to come out
