difference between wide and narrow certain-teed spring cover

A handy person from nyc says:
Was wondering what the difference is between the wide and narrow spring covers for the certain-teed window spring? Also wondering what the difference is between the old style and new style shoe? We've got the certain-teed windwo spring with the 504 springs.

Thanks.

Thanks for posting. The 15-156 is 1-9/32" wide while the 15-185 is 1-1/4" wide. The difference between the pivot shoes are that the 15-192 has alignment nibs while the 15-155 has a smooth face.
