Help with Revell 1971 Boss Mustang 351

[Andrew McD]

Doing some preliminary test fitting and having a terrible time trying to get the front bumper  to fit.  There are no pins or notches to provide a secure fit .  I have scraped the chrome plating from the inside of the bumper in an effort to get a snug fit but to no avail.  I believe a number of people on this forum have built this kit and I'm looking for some advice on how to mount the front bumper.  Given its current lack of positive fit when glue comes into play and there is paint on the body I am not going to be happy with the result.

I have included some photos to show how the instructions say the bumper should mount and some crude mockup efforts with a bit of tape.  Not sure if it will be evident that the bumper just doesn't want to line up evenly where the ends wrap around.
