Re-wiring 98 for a 95-97 ECU

[Ray Sta.Juana]

Hi guys, for those of you who've done it, what did u use to convert the 18mm
rear sensor opening to accept the earlier 12mm senor? I've pretty much got
it figured out how to do the rest per instructions on SR20 Developments
website (thanx to those who pointed me in that diretion) The instructions
say to find a bushing or adapter, is there one I can buy or do I have to
make one? TIA
