Web Price
$6.66/ each
Ships from supplier. Expected to arrive on or before Tue. May 13.
May 13 wouldn't work for me. Unless...while waiting for it to be delivered I could drop the original engine. And if the rod still hasn't been delivered I could unbolt the transmission and bolt it on the new engine with a new clutchplate and throwout bearing. Which reminds me, are M96 flywheel bolts single use only? Haven't seen any references.
