I used these on my 69. Quality stainless parts, easy installation, well thought out. Its complete with nothing else to buy. Get the complete kit with filter. I believe its still $550 for eveything.
I'm using a narrowed rick's tank, DSE mini tubs, and G-bar 4 link. There is plenty of leeway with the rear braided lines to mount the filter in several different locations.
damn... i just read that you to have these installed first before you have you subframe connectors installed... i have the dse connectors already installed... i will call them today and see if this is a show stopper for this kit or hardlines
