Upper Lower Crankshaft / Crankcase seals
by Glenn from Havre De Grace, Maryland on June 01, 2016
I purchased two of these $2 seals as well as two tab locks that we $0.99 each but because the parts came from different warehouses I paid two shipping charges. In essence less than $6 worth of parts cost me about $31 to reach my house. The tab locks are no larger than a nickel but they packaged these two steel in a box that was 4X4X6. A waste of a box, not economical for me, even with dealer mark up I could have paid full retail value, had them the same day and saved $$$$. Fool me once, shame on me and there won't be a second chance. Sales should have told me there were two shipping charges.
