Can someone tell me what the thread size is on the connecting rod bolts? It appears as though it is a metric thread. Also, I need to purchase a couple of such bolts. Any ideas as to where to purchase? Thanks, John
They are 3/8 SAE threads I believe. That is standard fine thread. Is this a Jetfire engine or a Cutlass/f-85 engine? I have some extra Jetfire rod bolts but they are different than the other 215 engines.
Do you have a Rover eng? I guess those would be metric.
Should be able to determine thread type and size at somewhere that sells American and metric hardware. Home Depot, Lowe’s, a good auto parts store.
I finally determined that the thread size is 11/32-24. I decided to just go ahead and buy a set of ARP rod bolts, and that is the size that I got. Thanks to all who responded. John
