Midget Front Bumper Question

[patti morris <mgj2@globaldialog.com>]

I need to replace the front bumber bar on my '74 Midget that has the large 
rubber "sabrina" overiders. What is the difference between tis type bumper 
bar and the earlier type using the chome overider with rubber insert. The 
catalogs list a different number for the '74

Thanks!
