This listing is for quantity one rear (U-Joint) seal. For all 1953 to 1958 Buick Dynaflow transmissions, also fits 1959-60 Dynaflows but the seal is not as wide as the original but works fine. This is the seal I sell in all of my 1953-60 Buick Dynaflow overhaul and rebuilding kits. The seal is new, not NORS, and it is Buick P/N 1396464, a open type metal clad seal with a Nitrile sealing element. It was made by National recently in the USA (or Mexico), their P/N 470774. Seal dimensions are 2.066" OD X .375" wide for a 1.375" shaft.

I ship this item via USPS 1st Class Mail Parcel Service to any location that has a US zip code, this includes Alaska, Hawaii, Puerto Rico, the Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands and also any APO or FPO address. For an additional charge you can chose to have it shipped USPS Priority Mail instead. Either shipping method comes with insurance and full US free tracking and you will receive this tracking number which you can then track your order if needed. If USPS shows your package is not delivered you will receive either a full refund or I will immediately ship you an identical replacement part. I will also ship anywhere in the World via the US Postal Service except India. I will only ship to India via FedEx due to extreme problems with shipping via USPS.

The cut off date for Monday through Saturday shipping is 9:30 AM, Eastern Time. I personally operate by myself 7 days a week, 52 weeks a year and ship 6 days a week. Since USPS ships and moves product 7 days a week, the majority of domestic customers will receive their order via 1st Class Mail in 3-4 days and via Priority Mail in 2-3 days, rarely 5-7 days after PayPal payment, no matter what day it was paid for.

I have been selling new automatic transmission parts exclusively for vintage cars, 1946 to the mid 60's for over 43 years now, starting in 1977.  During this time I have accumulated over 30 tons of misc. mechanical car parts from the early 30's to the 70's. I am now starting to offer these parts for sale.
