For sale is a full set of (16) NOS 5232675 Ram Air IV lifters for the very rare 1969-70 GTO and Firebird. I looked each one over very well. I am getting extremely picky here but one has a casting mark way at the top of the lifter which rides above the lifter pocket. Will not not affect anything at all and clearly just cosmetic but wanted to point it out. These are far superior to the lifters the aftermarket suppliers list for RAIV engines. The aftermarket lifters do not have the deep pockets for the push rod or the correct internal valve. They totally throw off the correct valve train geometry the factory designed for these rare engines. I have 2 pictures which shows how much farther the push rod sits into the lifter pocket. Also how it changes the installed height of the push rod. The problems with aftermarket lifters is rampant right now so don't go cheap on the lifters. You will need to do your motor all over again. Available much cheaper purchased locally.  These will be sent insured with signature confirmation as per Ebay seller rules. Mu Free shipping and payment in 3 days by PayPal or cash in person.  Thanks.
