I have a set of 69E MFI throttle bodies and magstacks in nice shape. These are one year only bolt pattern. I.E. They mate to each other and work as a pair on all the MFI cars, but you can't mix and match the 69 stacks with other year throttle bodies and vice versa. What is the current value of these?

Regards,

PS. I am restoring a 71E and I'm looking for a nice set of 71E throttle bodies. I already have the stacks, etc.
