First of all, congratulations on getting yourself an early Christmas present - - it opens up all whole new spectrum of performance parts, trim, doo-dads and stuff that people can give to you for the holidays.
It's not uncommon for the plastic nose/tail caps to crack with age and there are a variety of new materials that you can buy to replace the factory parts. Ecklers, Mid America and many of the sponsors of this forum sell replacement parts - - you can get hard fiberglass to achieve a seamless appearance, or a couple different types of flexible factory-like products.
Use the "search" feature of this forum - - undoubtedly, you'll find several threads discussing the merits of each as well as the best way to do the installation.
Best wishes for the Holidays !
