I hope the Cardone is a nice unit for you and it works well! I understand. When I returned my core I opted to NOT buy their label and shipped back my core with a UPS label I bought through PirateShip.com. Was around $35. I don’t know if I saved any money— can’t remember what Bluetop was charging for the included core label. Probably not.
I also left my old pitman arm on the steering gear. It was no value to me and Bluetop was adamant in their FAQ to not damage the core or you won’t get the full core back —
Aye aye captain, you got it! You can have the arm too.
Once you get all finished up with your install and work I’m interested how you make out.
