WGP Trilogy Pump Springs

[Cdn_Cuda]

Picked up a nice Custom half block Trilogy pump. In dissecting it I noticed the main spring is tiny, like this person used a valve spring instead of a main spring. I know the valve springs are Spyder spring, but these can use standard cocker main spring. Correct?

Correct

I dont know if you have all the parts already but I am making a 3d printed bolt sled and bolt for my halfblock trilogy in case you want one let me know.
might take couple of weeks but its next on my 3d project list

I’ve ended up with an extra half block bolt, but when i switch the original bolt with a different one I am getting binding issues. The bolt pin looks like it’s been through a blender as well.

So I’d definitely be interested in a bolt sled.
