hey guys i didn't really know where to go with this but i found out that injector clips from old honda accords (89 i believe) fit perfectly on dsm 390s. i assume they fit 450s also but i'm too lazy to try it. just thought i'd put the word out.

 

you can use obd1 and 2 clips.. here is the mod for the injector.. Just use some small side cutters and have at it. all you need to trim is the small tab inside the injector.

 

OBD2 injectors require a bit more work. OBD1 is a cakewalk.

here is an OBD2 how-to.
