AS I see the options there are four, Compost single mount ,double mount, stock replacement , or 4 custom steel . i need the caddy daddy ride, old age has overtaken my back. The only thing mechancial that I have over looked is the Dif and rear spring, Having seen a few spring failures and not wanting to ruin a weekend witha blown rear end I will be doing both as soon as that ship comes in , of course ai will be at the airport or carshow. My C$4 has a broken motor and that will be back in a few weeks. So speed is not an issue here. I like the thought of the double hung rear spring removing the load on the rear carrier. This a low and slow C3 so the racer spring is not in play. Please advise. I am sure that there are diverse opinions out there and all are welcome. Thanks , Placerville Will.
