Penske 7800 Quarter Midget Springs

[Dash]

Hey guys, after searching around a little I have come up with no results to getting springs for this damper. The free length of the spring is roughly 7.25 inches and the ID is 1.63 inches based on Kaz Technologies's cad model. All the springs that I have found for this ID are 3 or 5 inches free length.

Anyone got a good source for finding springs to fit these?

And after some more looking it appears that the whole body of the damper is threaded, which is not shown well in the CAD model. SO going to buy 5" springs and machine a 1" spacer to make it fit so we can do preload if needed.
