I would try a high quality VED and get into a routine of 10 to 15 minutes a day active use. The VED's at the sex shops or online are not the best help for getting your length back. I developed Peyronies Disease after using Trimix so now I'm on the PD Forum besides this one.
Many of the men on the PD Forum use a Three Tube VED and a 26 week Protocol developed by a Urology Clinic in Birmingham, AL. The Three Tube VED has three tubes of different sizes that fit inside each other, you start with the smallest diameter and move up to a larger one as your body recovers. There are both manual and battery powered models.
After using one for about 6 weeks, I can definitely tell a difference in that my scar tissue has stopped growing and I am regaining some length back. The VED that I'm using will cost about $225.
I can give you the name/model of the brand if you are interested
