Long story short I am rebuilding a 1990 5.0 non HO motor to go into my 1968 coup. The problem is I keep getting the wrong rings. The pistons I have are flat tops (original to the motor) with 1.5 MM compression rings and a 4 mm oil control rings. Every time I order rings I get ones that are too wide and will not fit in the ring lands. What is the deal I have tried three different places and I keep geting the wrong ones. Do I have the wrong pistons for this motor or are all the parts places in my town full of crap.

Thanks
Anthony

 

A parts house normally autozone or equal dont know jack, they have to know exact yr blah blah blah for winshrild wiper fluid lol, better off ordering from summit or somthing of the sort!

Start with this part number SLP-E-458K its for stock bore pistons, i bet you have the regular standard rings not metric!
