Dont know how to post a link, not great with computers yet. Its on the TRS website, look under Complete retro kits, scroll down a ways and it will be a quik retro for the Spyder/Spec-d Housings. Basically it is the H1s, the have just made an adapter bracket for the housings to where you can remove Spyder Projectors and replace with the Mini H1s. basically same kit that we have discussed here for retro on the OEM Housing, just made specific for the Aftermarket Headlight housings. Hopefully that answered your question.
