REFLECTORS on fork?  74 DT360.   Looking for the original ones with alum base.  May have to paint one of the black ones though that seem more available. 

Talk to me goose.

 

DEET?
 

If you don't mind using copies, there's lot of them in Indonesian markets.
Have bought them in the past .Down side is they are not so flashing and screwing it needs good attention or you may ruin them.
I apply bit of sealant on the tiny threads, just don't use those red/blue lock tide.

Also
Ask them for the length of threaded part,if you going to use the black rubber cushion underneath,they needs the bit longer thread .
I hv tried using those rubber cushion underneath on my TS C but the threaded stem seems short.

I might have some used ones if you have the diameter and markings you want to match... 
 

If you know what text is on the front/rear, search the marketplaces under this as well, as seller might not know they were for Yamahas.

What about these, or are you after new? You'll likely already know, but same part was used on a couple of hundred models.

MikesXS and other stores have repros cheap.  Here's one of many.  www.mikesxs.net/reflector-front-fork-honda-1.html

Dr ATV sells OEM Honda reflectors and some look really close to the original (might be the same?) with the aluminum base and not the "plastic chrome".

Thanks! Some great options I did not see. I think I'm going to p/u the ones listed in ebay link and a set from Mike's since they are so cheap just to see how close they are.

Here are the dimensions for future reference. This reflector is from my 74 DT125A, stock bike. Partzilla list same reflector for 360. 355-85111-01
