I know there are a lot of topics, but my basic question is on a 69 with a BB and NEW stock BB springs.

I was considering Summit IAS shocks (EDL-33016) at ~$73 each.

OR, should I go with an adjustable for more money?

Thanks for any suggestions.

Adjustable front/rear shocks will go along way in consistent track performance. I like the QA1 single adj. in front and any good double adj. in rear! Amazing how much stiffer front shocks get with each click! Good luck!
