I've managed to do more than I intended, but it feels like the right move. This '74 currently has adjustable hydraulic springs on the rear and eye-to-eye is about 14.5". Looking to replace these with ones not fitted with the hydraulic separate ugly tank or find a way to adjust the tanks to fall more inward. Any tips or ideas with replacing the rear shocks would be great! For now, sticking with the funky 16" on the back! Thank you for all the help along the way. What a solid community.
