Yeah i had a trailer load of stripped 'clean' bases and engines i took in the other day. $1.20 a KG. Had some flywheels and I/C blocks and some old corroded motor i couldnt be bothered with 36c a KG.
The local yard would be a good spot. Offer up a crisp $20 for a victa with a decent base.
Steel base or alloy. It matters with the catcher. Only the late model ones use the same catcher as the steel base.
