Ken the knock offs on the LH side of the car should have conventional RH threads. The knock offs on the RH side of the car should have LH threads. With them mounted as such they will attempt to tighten as the car rolls forward (??)

Another good way to remember which is which...always LOOSEN the knock offs by striking the ears so the knock off turns toward the FRONT of the car, no matter which side they're on. The right side of the car has lefthand threads in the knock offs, and the left side, right hand threads.

You may want to contact Lynn Parks at Trigo Wheels for your knockoff. Lynn made my wheels on #770, the adapters and knock off's, too. He also can supply adapters, wheels and knock offs for WAW wheels, and SPF wheels, as well as his own Trigo brand. He also sells polished stainless steel knocks offs, as I have purchased from him. I use my polished knock offs for street and my original knock offs for track...I've drilled the originals for safety wire as most sanctioning/sponsoring bodies require them to be safety wired.

Other things I've found out about knock off wheels/spinners... No matter what anyone says...safety wire will not - repeat WILL NOT - prevent a knock off from coming off! Safety wire should be installed as if it were trying to pull the knock off loose...not trying to prevent it from loosening. In this manner, you can check the wire for slack...indicating the knock off has loosened...and then whack your knock off a couple of time with your lead hammer to retighten it. Works great... Also...plan on removing your knock offs at least once a year...use some anti-sieze on the drive pins, knock off threads, and on the conical mating surfaces to prevent them from seizing up. Purchase a lead hammer, if you don't already have one. A dead blow hammer just can't strike hard enough to move the knock off. Don't over tighten the knock off...a couple of revolutions after it makes contact with the wheel is sufficient to hold them on. Thereafter, once a month, whack a couple of the ears with your lead hammer to make sure it's tight.

Now...before I get 6000 messages saying I don't know what I'm talking about, I got all this information straight from the winningest race car driver ever to come out of South Africa. He drove for the Willment Racing team, and had more miles at better than 100 MPH than most of us have driven in our entire lives...at any speed:

FF,
Did you write all that info down when you were told or did you recall it from memory?
I hope you recorded your conversation with Bob. Besides he only drove the car what does he know.

Correction...two ears...not two full revolutions...my apologies. I had been hammering mine on way too hard when Dennis O showed me it only needs a couple of ears turn once it makes contact. You'll hear the sound change when the wheel bottoms out on the adapter. I've had #770 for 6 years now and never had a problem removing my knock offs or wheels.

No...I didn't record it, nor write it down... But, I've been privy to pretty much the same speech from Bob with at least four or five different owners who - for one reason or another - just couldn't get the hang of lefty-righty-righty-lefty. One poor fella...who shall remain nameless...worked for several months to remove a knock off with only a dead blow hammer! When another SPF owner visited him, he took hs own lead hammer and had the knock off removed in less than 15 minutes!

I sure miss Bob...he had forgotten more about these cars than most of us will ever know! He was truly one of a kind!

Mmmm...This is contrary to what I've been told, and seen on cars from assemblers like HRE, Snakepit, and his son Dennis' shop. I was told safety-wire to prevent loosening with a bit of slack, and check before every ride. Evidence of tightening requires a whack to the rear and re-wiring.
In fact, ERA has the procedure on their site:http://www.erareplicas.com/427man/wheels/index.htm
