I bought these at the Spring Fling -but won't use them

These are either older or road bike used on BMX (yeah, we all did it.)

Takagi Ultra Dyno alloy three piece cranks

For square taper bottom bracket spindles

I measure approximately 170mm between the pivot hole and pedal hole centers

This fits the OLD School 130 BCD chainrings -won't fit a modern 110 or 104 BCD chainwheel.

For that reason, I'll throw in the Blue no-name 42 teeth lightweight alloy chainring I have.
Was gonna keep it until I realized it is 130 too.

No bolts, sorry.  I'll send a pair of functional but rusted chrome face ones if you need to hold your sprocket on. 
Let me know when you pay.
