The one I built myself for less than $50 using a C5 tensioner pulley, flat stock, steel tubing, both from Ace. Just some simple measuring to put the pulley wherever you want it.

We wiped one up with some stainless angle and flat stock also. Bought a new pully at NAPA and whne we set it up used the original belt for the thing. Its not that hard! wro87
I apologize, I took way too much for granted here. By the time I went out and got the materials, charged you labor and shipped it you would be close to what you could just buy it for.
I think the A.I.R. pully you are currently referring to as the cheaper one is from Midamerica. It's cheaper because it uses a plastic pully. I don't know much on it though. Breathless has one with a metal pully for around 200ish. If it was me, I would go ahead with the metal pully.
I didn't use a welder to make mine - just a drill, tape measure and a hack saw. I basically copied the Breathless design. A few feet of 1x.5 solid aluminum, a few cheap sockets to use as spacers and a pulley from McMaster-Carr ($6). I think it was <$50 after all was complete.
Both my 90 and dad's 86 have the same assembly. I have about 30k miles on mine with no issues.
I would rather use a shorter accessory belt and relocate my alternator than use those clunky bypass kits. It can't be that hard to fab up if you always have scrap sheet metal laying around...
Assuming this was directed at my comment - it's 2 aluminum bars and a pulley. Not exactly the space shuttle.
I'm sure the Breathless piece is machined better and has a higher quality appearance Although I have never seen one in person, I am sure it is worth the $162 - materials and fabrication time is not cheap these days.
For me, though, I care very little about nifty polished parts under the hood. My bracket works, its strong, its cheap and it gives me room to work. I am shocked that my $6 pulley lasted so long... my Dad and I guessed it was going to fail before the next oil change but we were surprised.

main bracket (3/8'' alum) and front brace (1/8 x 1'' s.s.)...shiny horizontal bar is machinist's scale, not part of ***'y - ref only.
side brace (1/8 x 1'' s.s.) and rear ''curved tube'' brace (galv steel to match header heat shield, fits around oem a.i.r. pipe...straight rear brace would work if no a.i.r. pipe is in the way)
uses serp belt abt 2'' shorter than oem...leaves slightly more room between alt/hood than oem pump/hood.
guy that made this is currently having lunch in ''bad-bag'', also breakfast and dinner...there is one locally that owner never got ''round tu-it'' before makin the ''big'' mistake, i'm tryin to buy/ borrow, will make layout available to members if/when...have an early version on my car (very slight diff) and lt1 elec smog pump mounted by spare tire, still ''green'' but 6 lbs lighter+ weight reloc.
