UNUSED 1963 - 1979 Corvette, Dick Guldstrand Long Rear Spring Bolt Kit (Discontinued). Bolts are 7 13/16 " under head length (UHL) with 5/8" NF thread. Steel/Nylok Nuts and Steel Lower Cushion Retainers included. Instruction Sheet included. Never installed or used. Stored in a plastic bag in a plastic tub and kept inside.
Will require that the stock support washers be enlarged for the 5/8" bolts from the 9/16" standard. Will NOT fit stock rubber cushions (Is intended for racing application).
This bolt kit is designed to be used with high performance steel springs for road racing or high performance vehicles with lowered suspension. The long threaded area of the bolts allows ride height to be adjusted as necessary. Wheel alignment must be set when ride height adjustments are made. Read the Instruction Sheet for more details.
I bought to use on my 1963 Corvette with a DG Gymkhana rear spring that I sold.
