Steering issue

[Dewey72]

Hey guys i got a 72 short box with a cummins swap and dana 60 front. My issue is it likes to bump steer with the added weight. Its running 35" and 4" skyjacker front springs. Wound it be worth it do a crossover steering? this truck never really goes off road. I added a Bilstein stabilizer that helped a bit but still would like it better. Not really wanting to put on stiffer springs like the ride now. Thanks for any input
