These blades are a bit thinner in thickness than the original factory blades. They will be a bit loose in the throttle shaft slot. If you are purchasing these blades you will need to purchase the throttle shaft these blades fit in. Under the listing for the front or rear carb throttle shaft for $38.00 read the description further, you will see that when you place the order for the aftermarket throttle shaft that the cost is $30.00 each. Make a note in the comment section of the order and will refund you the $8.00 cost difference for the shaft.
Excellent quality. Several manufactures have attempted this over the years. This is a precision fit item. Although this is an exact copy of the original, installation in a used throttlebody does not guarantee a perfect result. I include a small qantity of DAG213 which will be required to seal these perfectly. It looks like black paint and is applied to the edges of the throttleblades after installation. Screws included. You need to glass bead all surfaces prior to assembly. If you do not have the equipment available to glass bead the parts, you have another option. I can restore your throttlebodies for you. Usually, I find customers do not need new throttleblades when I inspect them. When I restore a pair of end throttlebodies, I charge $130.00 a pair (both end throttlebodies.) This service includes pulling yours apart, inspecting shaft for wear, glass beading all parts, paint throttlebody, re-assemble, seal blades, install new torsion springs. If your passenger side levers are not damaged, I will replace them with replated originals. Price includes return postage back if you are in USA. E-mail me for details. Usually I have a quick turn-around...just a few days.
