The TL ones will fit GS with flange ... Now for flanges -
I have 1 last flange - high exit ... can be modded (by me - so I need to know at order time) to fit 01+ else will fit 89-00 ... High exit, and you'd have to re rivet the end cap to point it right.
If these are going to take over the spot vacated by the wiley co ... Yea I dunno these are $$$ ... I may be able to re make flanges ... 25-30 minimum ... but yea ... Once I commit to making it ... I will, but dont count on times ... So dont go buy these and jump on my back. If there is 25-30, then as 1 lot we can get it and I'll go about making flanges. As the last time ...
Cool.

BTW The freaking things are oval ...
