Alternative Shocks for DB01. GPM /B4 ones?

[pete2222]

Has anyone fitted the shocks from an associated B4 onto a DB01 Durga?
I am asking since I have a spare set of B4 shocks, and wondered if they might fit and be an appropriate upgrade.

Second, are the GPM threaded shocks that are available for the Durga thought to be any good. Some of these came as spare with my second hand Durga. One has the end snapped off, but the they look good. I’m tempted to get a new front set, or a replacement end piece (is this possible)?

Thanks for any advice, much appreciated.
