Wanted Xt m737 brifter right or spare spring.

[Shaznaz786]

Hi there fellow retrobikers.
So, I bought a dawes " the edge" mountain bike.. xt m737 spec..
Bike had no pedals so unable to test..
Anyhow right shifter doesn't work. There is a broken spring..
Pic attached..
Anyone have one of these?
Or failing that a serviceable m737 right brifter will do.
Otherwise shifter is mechanically sound internally.
Thanks..
