Hi there- thanks for posting!

It looks like you have a Series 390-29 (29 represents the metal channel length) with a 1-1/8" depth shoe, which is our 15-001 shoe. Please carefully compare our measurements and information to what you have. The spring weight will be the 2840 option at checkout.

Please get back to us if you have any questions.
