Inner te TE183L+R
Outers TE187L+R for 12mm threads or TE437L+R for 14mm threads


Te437 are easy to get... same as 1600 and I think vanette
183 and 187 will be harder

I'm chasing up manufacturers amd people all over the world right now for old stock and if people will make new ones
Still looking for samples of uppers, lowers and TE187L+R
Already have 183's and if need be good second hand parts but would like newies.
