[Fot] TR-3/4 main cap bolts / ARP

[Tony Drews]

Anyone have info on dimensions for TR-4 main cap bolts?  The manual 
shows 1/2" UNC but not the length.  I'm trying to figure out what ARP 
bolts you would buy to replace the stock bolts, and also one that's 
1/2" longer to allow for "strapping" the center main.  If I had the 
dimensions (length) I could try to cross reference the engines that 
ARP lists main cap bolts for.

Thanks in advance,
