700r4 shift indicator assembly?

[vintovka]

Well trying to finish what i could not afford the shop to do. I have an 87 gmc tilt column they rebuilt with the 700r4 column shift. They rebuilt it fine but need an assembly diagram to reassemble the shift indicator. Have all the parts and can get pointer in housing and working . BUT Theres an odd looking white plastic part with two spring arms that has me stumped. Been on the net for 2 days looking for a diagram to no avail. Its NOT the dash mounted indicator with the cable, Thanks
