I have simply cut 1 1/2 loops from the rebound spring. Mount spring with the cut loop down. I have been doing this on +4's for over 20 years. Bill Fink and The Chief Engineer for Morgan (forget his name) came up with this idea. The "Rutherford" rebound spring is a neater item in that it is finished with a proper loop. Not just cut and installed as I do. Lately, since Peter Ballard explained "Hooke's Law" I have installed the main spring without the rebound spring and let the Morgan sit on all 4 wheels. Measure the space for the Rebound spring. Add a bit (+1/2"?)(Tim Harris's idea) and cut to fit. The main spring is Peter Mulberry's 140 in/lb and thrust bearing. I replaced the Suplex Kit with this system on My +8. My feeling is the engine is too heavy for the Suplex Kit. I will use the Suplex Kit on My DHC with the lighter Zetec engine. I tested the Suplex kit with the DHC and liked the results.
