When I bought my 240z it came with a pole of new parts. For some reason I have 6 struts tubes.   I’m replacing struts and springs on my 73 240z. 

Im not going to track it. Street driving is all I’m going to do. Maybe put down to cars and coffee. 

My understanding is KYBs are better, but I only have 2. 

Which would be better?  2 KYBs and 2 Gabriels or 4 gabriels?  If it’s 2 and two, which should go up front?

The rear makes the most difference, put the KYB's there.
