Here's some info. EDIT The mr gasket light spring kit is 925B iirc. The MP kit is P2932675. the crane kit (which is no longer available new) had a plain spring a yellow spring & an orange spring & they recommended to always keep the OE light spring & sub in something instead for the heavy spring with the long loop on one end.
