i use this one from moroso: http://store.summitracing.com/partdetail.asp?part=MOR%2D63810&autoview=sku
you can mount it driver or pass side, high or low.
here's a pic of it installed on my engine: http://home.neo.rr.com/turbo68/eng/P1010032.JPG
i just installed the same thing in my '68.
the only tip i can pass along is that the main loop had 'sprung' a little bit. we had to put a strap near the botton and pull it in to fit. other then that, no problems.
