suggestions for aftermarket parts?

I just wanna ask a few suggestions on which product or brand to get to make my kits look better?

1. bonnet pins (thinking of sakatsu)
2. windsheild wipers (have no idea...)
3. the metal parts of seatbelts (have no idea which ones..)

And is there any other bits on the body cept antenna or fuel caps??

How bout some brake discs? There are some photo-etched stuff that you can buy for your cars, they have one for the ENZO and some other cars, Check out the photo-etched kits and see what you like. Check out

Sakatsu or Renaissance bonnet pins look amazing.

Modelers make great wipers, prepainted in black too!
