[Fot] TR6 rod questions

[Greg Blake]

I am building another TR6 motor. This time a warmed up motor for a street car. This is a '73 and upon disassembly, I found the number 3 rod has been replaced at one point in the past. The replacement is an early(?) rod w/o the hole above the otherwise blind cap bolt. 

Should I be searching for a replacement of this early rod to switch it to the later style with the hole or 5 replacements w/o the hole?  

I searched the list archives and could not find much debate on the merits of the two styles of rod. 

Thanks

Greg
