Hi Mitchell! Since you didn't mention the specific vehicle, it's hard to tell for sure. To give you the correct information I would need the year, make, model and engine size of the vehicle.
Is this supposed to be the input seal or the outpit seal for a 1990 k1500 4.3l ? I only ask cause I when to get this with my clutch kit also but its saying the output and that not correct with what I'm seeing it a muck latter one for that. I've domey research it was given toe as the input but the input is actually 4529N for national seals. I do a lot of business there and have commercial account usage there's also this is a shame I can't even put my truck back together now and if it has to be ordered I can't wait any longer to be without a vehicle I will call corporate if it come to that this mistake is going to cost me my lively hood because I was given the incorrect part

Hi Shane, I can understand your concern that you have received an incorrect item. The National oil seal - Part #4528N is an output shaft seal and the part #4529N is an input shaft seal for your 1990 Chevrolet K1500 4.3L. I would suggest that you call us at: 1-877-ADVANCE (238-2623) or contact our "Live Chat" support and one of our representatives will gladly assist you with incorrect item.
I have a 1997 GMC Sonoma 4.3L V6 Vortex automatic transmission. Will this fit?
Verified Reply - Solomon
No, Nat! This National Oil Seal (Part No. 4528N) does not fit your 1997 GMC Sonoma 4.3 L. However, we do have an exact fit Oil Seal available online for your vehicle (automatic transmission 4L60-E) and the part number is 4934. Please enter your vehicle on our website and search for this part to check the fitment.
I have a New Venture 1500 transmission, (Get Rag 290 5 sp) Is this the correct Output Shaft Seal ?
