I bought a set of clear lenses headlights to replace the old units.
After reading about it being sh**part i wasn't optimistic when I realised the boxes they arrived in.
However, 9 months later and they are still in perfect condition.
I also bought a bunch of fuel filters from them when I started running veg oil as I was told they might start to go quickly as it cleared out junk in the system.
I was also pleased with these, good fit, no problems at all.
I think it may be a case of limit to non-moving parts and you'll be ok.
