Can anyone confirm the width of these two spacers. The ones pictured came from a GPz1100 Unitrac. They are both on the left hand side of the bike, one at the front & one at the rear. This engine is now fitted in a 'J' frame & I need to be sure these are the correct size.




Thank you!

The long spacer (LHS) is 55mm in length
The short spacer (RHS) is 30mm in length
Stud is 12mm OD

Front spacer is not circular but a horseshoe shape and is 4.5mm thick
Rear bracket before paint is 4.5mm thick (the one pictured with the stop switch mount)

P.S.
My No. 4 exhaust header is dangerously close to the front frame tube so it has to be dead right or better!!!

Thanks again Al,
That is a great help. Only need to fit engine to sort out chain alignment & that large 55mm spacer is crucial. Luckily the one in there is 55mm. I'm just pleased to know I have the correct size. Thankyou Thankyou.
