Lost one today, what can i use in place of one, are they required or no. i called shops they were all in a set of 16 and thats not what im needing.

 

Well yes it's required since it holds the RR on and you adjust them with it..
Not sure what you could use in place of one except another one.. you MIGHT get by with a stock rocker nut for a few days?

 

If its a stock nut, I can snail mail you one in the morning. LMK. As far as i know though, polylocks (roller rockers) are only sold in sets of 8 or 16

 

Which rockers are you using? I have the CC 1.6 ProMags and ended up having to replace one. Depending on how much a set of 16 nuts are, it might be cheaper to just buy another rocker and nut and have a spare rocker laying around just incase. It was about $25 plus shipping if I remember correctly. Like Mtrhds94Z said, you might be able to get away with using a stock nut for a little while but I would use it long.

 

i meannt i have stock 1.5 rr from the factory and lost one? I dont have any HP RR yet

 

Do you mean that you have stock 1.5 stamped steel rockers?
Or do you have an LT4 with stock roller rockers?[RR means 'roller rockers'?]
If it's a stock nut you need, I'd take Spinner up on his offer there..

 

Stock LT1 with factory stamped arms.

 

At Carquest you can buy a single nut.... At least here they do.....

 

I'd ask Spinner to mail you one [or 2!]then.. he offered to..

 

Im not sure what size a spark plug socket is thats what size fits the nuts, would a nut off a E7 Ford head, rocker arm work im thinkin their the same size?

 

5/8ths......
