Hey guys,

I am on the look out for some adj uppers for my 89. The Edelbrock/QA1 pieces look really good as they use the stock diff bushing and spherical ends on the body side. Any other recommendations? I need the ability to adjust my pinion angle so they must be adjustable.

ps let me know if you have a set for sale!

Thanks!

The QA1's look like the Edelbrocks we put in Pauls fox. Impressed with the quality and fit.

ensure your lower control arms are 17-5/8" centre to centre if you want to be able to adjust the pinion angle. Some are longer, which makes it impossible to hit the right angle due to not enough thread length.

IMO lower arms should have at least one spherical bearing, if not 2. Uppers - OEM rubber on axle, spherical on other end.

Lots of double poly stuff out there can stress the upper and lower torque boxes due to non compliance, making your $250 arms cause $500 worth of damage.
