Hi Evan, thanks! yes I remember this chap, although I can't recall if those projectors were ever assembled and instead meant as a replacement for another set he had (he had the first ever set in silver if memory serves well!). I'm hoping those came with the H1 bulb mounting adapter and other hardware?

For the lens assembly you need a A+B epoxy rated/tested at 100dC. Surface preparation for both the lens and bezel requires decreasing with a pure acetone before bonding. Assembling and curing should be carried at room temp (indoor, 21dC).

ps. Welcome to the forum! Seen pics in the general section, great looking boxster

Yes, thankfully the kit is complete and still looks brand new!

Thanks, I'll look into it. Unfortunately most high-temperature a+b epoxy glues I found don't bond very well with glass. Maybe JB Weld?

I'm also thinking of using the type of angel eyes that I'm currently using as they automatically dim when you turn on the hid-lights. This is to prevent a blinding light-intensity at night, but maybe the hole-pattern in the bezel should be sufficient.

Good news Evan. Was worried, I knew the kit was parted out but didn't remember if all parts we're shipped out. If you are missing anything just shoot me a PM and I'll get this sorted.

For the A+B, use this if you can get some locally. Will bond metals & glass and perform in both high & low temps (in the commercial grade epoxy anyway).

Thanks again Nine8Six, you're a lifesaver!

Maybe I'm overthinking this, so forgive me if this is a stupid question...

When using the spacer, how is the projector assembly secured against the projector bowl with the tightening ring tightened?



Note, I don't have the tiny square in the projector bowl anymore, had to Dremel it away for the current projectors.

Hi Evan, see if below visual is of any help to you. The missing tiny square isn't much of an issue although it would have been nice to have. In all honesty I've never tried fitting a set without it so trial & error apply here. Mount as per visual below first and see if you can level the beam projection high enough using OEM's adjustments in both X/Y axis. If all goes well with the beam adjustments, "Lock-Tight fluid" on the thread and move on! GL

Note: Its important to not exceed 23~23.5mm for the OD on the reflector's mounting hole.

Thank you again! This clears it up. If I remember correctly, the enlarged holes for my current projectors are 20mm in diameter, so can still be enlarged to exactly 23mm.
