I have run stock 1968 7X15 rally rims and stock 69 8X15 rims on a 1967 427 Coupe with no problems.....so you don't "need" offset trailing arms unless you are planning to race your car. Significant side loading (lateral gees) sill deflect your arms and tires enough to cause contact.
That said....if you "want" them, then my racecar uses offset trailing arms from Duntov Motor Co., so call Alan Sevadjian and ask for price. if they are good enough for a racecar, then they will suffice for any street applications
I got mine from VBP. I like the way they look, solid steel with bracing. I'm just in the process of putting them on, so can't say much about the fit etc. Purchased mine when they had a 20% off sale. One thing you will ave to do is cut off the rubber over-ride bumper brackets. Another thing is you don't need to keep track of the shim thickness as the new TAs will be different than the old ones.
Now you've got all three with OKs. What ya gonna do now??
The stock TA can be made to have quite a bit of extra clearance by moving the parking brake cable to the top of the TA. With the bracket gone and the cable out of the way, you may not need the high dollar TAs. Good references if you search the C3 forums. JohnZ has also posted a pic of the mpd to a thread on this forum in the last month or two...

(new brackets to weld to the top are available through most of the suppliers for a couple of dollars. Note also that at least one of the offset TAs sold send the cable over the top too)

Few days ago I got my new catalog from Van Steel. It says their offset TA can accept 2 inches over the standard tire size and still give you the same recommended factory alignment. This added off-set dimension allows the weight to be centered so you get less wear and tear on the wheel bearings. They also have a double off-set TA
Here are some pics of my setup which includes the dragvette suspension, VBP (420Lb) monospring, offset HD vansteel trailing arms, carbon fiber halfshafts, 1" swaybar, 8" wheels and 235x60x15 tires. If the spring is shortened and the sway bar removed or bent for clearence, I could put 10" wheels on the car. Hope this helps.

Hey, don't mean to get off of wheel size, but I noticed your 6 link. I have installed this system on my 66 and have encountered a slight problem with the outer half-shaft u-joints binding against their corresponding flanges when rotated towards the top and the suspension all the way down, (on a lift). Steve said it shouldn't be a problem, but it worries me, as I don't like things binding like that. Please let me know if you encounter the same problem. I am also looking for wheel size info as I have offset arms and wilwood brakes.
thanks

That outer U-joint binding will occur on almost any Corvette with the suspension in full rebound, especially if it doesn't have the original shocks (which incorporate the stock rebound limiter). If you don't "get air", don't worry about it.
