 Vibration at 110kms/hr

I didn't have a vibration before the conversion, now I do. Also whenever I go over a small bump it is clunking.
From the feel (and noise) its coming from the back left hand side of the car.
Its like clockwork, only at and over 110kms/hr. Doesn't matter if the car is in 5th or neutral.
I had my intake pipe done this morning (shiny!), and got them to check my exhaust at the same time, they extended a mount or something or another, but it didn't make a lick of difference, so I'm pretty sure its not exhaust.
I'll have a good look at my rear left wheel tonight, and maybe check the bolts from tailshaft to diff. Don't know what it would be on that wheel as I havn't taken it off or anything (closest I got was the tailshaft).
What could it be?
What else should I check?
I might take the wheel off and have a look at the bits behind it. Or just jack the wheel off the ground and see if I can wobble it by hand.

i havent had a good look myself but there's bound to be a ball joint of some description being IRS, otherwise bushes, torsion bar bushes, or an outside guess C.V joint ..
good to hear it's all up n running too, how close did the headers end up getting to the rails? any other major obstacles? if it has already been discussed on another thread feel free to point me there

That'll most likely be your new tailshaft Pete. Out of balance and doesn't vibrate until it hits 110 exactly.
Did you get it balanced?
Is it two piece? If so did you bolt it up incorrectly and get it 90,180 or 270 degrees out?

Was my tailshaft bolts. Jacked up the left rear to shake the wheel, was rock solid. So I shook the tailshaft.
ALL 4 bolts were finger loose!!!
So I did 'em up as tight as I could by hand, then had to drive to basketball. Got back and tightened 'em up as tight as I could with some spanners. Not sure how long they'll stay tight though.
Whats a good way to tighten these 4 bolts??
Paul, the tailshaft was the original supra 2 peice ... although it might not be original as someone before me swapped the car from auto to manual. We made the engine mounts so that we didn't need to move the gearbox mounts. They use the same ones, so the tailshaft just slotted in.

Scotty, had to get the exhaust manifolds from a soarer (is a crown engine). They fit in great, clears the steering drive shaft thingy nicely, and actually could be attached to the engine while it was lowered in.
Other major problems we knew we'd get - engine mounts, bellhousing, computer.

Thanks craig, I think I've got some lock tight in my toolkit for my remote control car (runs on nitro methane). I'll give it a go if they come undone again (will check in a week or so)
