Trailing arms

Hi all,

I'm in the middle of sorting out the rear suspension bits ready to reassemble, but I'm a bit stuck. The trailing arms I have are for the 4 speed axle, but I'm putting in a 5 speed axle. According to parts listings, these are different parts with different numbers.
Are they interchangeable, or am I going to need to source a new pair?

TIA

Should be the same length (±483mm for the 5 speed type)
Only the later type have a bracket welded to the rear.

Together with a bracket ...

... bolted to the axle itself ...

... this lessens axle wind-up under load/acceleration.

Thanks for the info, I'll go and measure mine to check. I didn't know about the brackets.
Funnily enough, I am right in the middle of de-rusting the brackets that fit to the axle, and I was wondering how they worked - so that's two queries solved for the price of one!

I might see if I can pick up a pair on fleabay cheaply, otherwise I'll just paint up and use the ones I have.
