pinion angle or driveline?

I had that issue too. If an axle is bent enough to see it will cause hell.
I think runout tolerance is .002 max on either the face of the flange or the top. Pull the brake drum off and check the flange with a dial indicator on the edge and the face.

if the right then wobbles it is a bent rim or bad tire.

i did not see if someone posted this but the factory pinion angle is 5 degrees or close to it. 4 is also fine meaning that if you lower your car 2" you do not need to change the pinion angle..

I did swap them out and it looked a little better, so I went for a ride and the 80 mph vibe showed up as usual.
Not sure if I would hear a growl above the exhaust growl.
I'm wondering if the driveshaft is just not up to task going 80mph at 2200 rpm with my gears and tires.

driveshaft runs uphill 4 to 5 degrees from the pinion.
you can get your shaft tested fir straightness.
the rear yoke might be bent a hair but you said your tire definitely wobbled on the left side so, that must be fixed first then tested before changing anything.

I had my DS shortened, straitened and balanced in prep for the T5 swap and then rechecked for balance after the vibes showed up.
I'll get a dial indicator this week sometime and check stuff out next weekend.

Read through all this, and noticed a lot of people having questions about their driveshafts and getting them balanced. Coleman and FastShafts both make driveshafts for racing in 1/2 inch increments. You can source them from Lane Automotive, Port City, Lefthander, Jegs, Summit. I use Coleman's in my racecar and spin them to 7800RPM without issue. I've also used Fastshafts in my modified and spun it over 8000RPM. They aren't that expensive, maybe $300 tops. Which is probably not much more than you're paying a local shop.
