The A1 ut s/arm has a smaller spindle and cant be used on the later ut`s .

I have a spare A1 s/arm in bits if you get stuck for anything ?

I will measure the A1 one tomorrow ,If i remember correctly the left side (chain side) is smaller O.D but i think it would be possible to have a coller/insert made up to accept the A 2 /A3 s/arm ?? the right side is the same .

What are you trying to do ? swap/match ? .

I bought a replacement swingarm and unfortunately didn't know they were model specific and just assumed that all unitrack model gpz's were the same so was hoping to do a mix and match if they are from different models.
Thanks John

I done the same ,but i had a spare A1 in the lock-up !! but then had to buy one off evilbay ! But there was a couple of A2 /3 s/arms for sale at the time ,about a month ago ,i got my one for £30 powder coated silver but with no adjusters or other bits ,but i just used all the best bits off the other two to make one good one .
I think there is one other s/arm complete on ebay £60 (i think) ,If you can not find it let me know and i will see if i still have it on my watched list ?
I think you could get a coller made up for the frame and then fit the A1 s/arm in ,but for the hassle and cost it would proberly be best to find the coorect s/arm ? if i can help just let me know ? Andy.....
