Hello Uncle, I didn't get them in my kit bolt bag and had to ask. They are 240mm I believe.
Others have had fitting difficulties due to not lining up or powdercoating not cleaned out.
Remember it's the sleeves that move in the bushes not the tightened bolt in the sleeves.
Ensure the bolt goes through each component separately. Top as well.
You could temporarily put in a shorter bolt to hold the other arm in place.
Perhaps if you start inserting at the bottom bush and rotate the whole carrier
from upright round to underneath as you tap the bolt head with a 'mechanics kiss'.
Rotating the carrier up and down may decrease the mis-alignment and allow passage of the bolt.
Forcible entry may damage the first few threads so you may want to file those smoother before or after.
These two threads have to be outside the nuts anyway and an IVA cover will hide your butchering!
We should now listen to what "Simon Says"

I had an issue with the "long bolt" found I could not line up all the holes with the crush tubes, then after struggling for a few hours gave up and went to bed. ! Then at 2am had an idea, got up and within 20 mins had done it !

Basically I removed the crush tubes from the bushes, then slotted the long bolt through, and after tapped back the crush tubes, repeated on the other side and went back to bed !
Hope this helps

I have had to strip the rear suspension down (did not build the car and Builder not built correctly) and had great difficulties getting the original bolt out of the hub carrier, the crush tubes were ok. Now I almost ready to put back together I need a replacement bolt. I believe it is m10, is this correct or is it an imperial size? the reason for the question is that the old bolt had to be removed with great force and will not go back in without forcing and an M10 bolt is the same. I would have thought it would just glide in but struggling to get more than the tip into the tube.

I know you didn't build the car and the previous owner didn't do a great job!

There are parts of the rear suspension which are handed, I think it is the lower wishbone and hub carrier?? They have a notch in the top and should be used on the offside (drivers). If these are the wrong side they are a Bu***r to line up and in fact don't (I know I made this mistake when building, until Richard pointed it out).

Worth checking???

if it is a size problem, eg the 10mm bolt will not slide through each component separately, then it is likely that the tube is either burred OR there are remnants of the corrosion that caused difficulty with the bolts extraction in the first place. Burring will be at the end of the tube and can be cleared with a 10mm drill (DO NOT GO DEEP. 1mm SUFFICIENT).

If it is corrosion (further in than the tube ends) you may need a reamer, although there is another "tech y" method, no John, not a hammer Smile, not this time anyway, Laugh. but its a little difficult to ex-plane on here, perhaps a phone call to the workshop?

If it is alignment, and the early chassis do need some help with alignment, you need a "bullet", easy enough to make, again phone, BUT you must make sure you have sorted the above before using it or you can really get stuck.
