Contact Sundown directly. Btw, PSI can make you a OEM drop-in.
"There are a few guy out there that can build our drop-ins (OEM style or customized) as they are authorized to buy our parts if you are in a hurry and our lead time is too long -- you must order through them and do all contact / follow-up with them. Doing business with any of the following builders is completely separate from doing business direct with us and their pricing may vary from ours
; but I can say we have done business with all of these guys for many years now and we are comfortable with their work.
They all have good feedback on the forums as well :
