About Toohey Parts collection
These parts came from an
abandoned warehouse in Louisville Kentucky, after G.W. Toohey closed his 15
parts stores in the Kentucky area in 2001

The Toohey parts stores were
closed in 2001 and the parts we have for sale are all new or remanufactured

About Shipping and Handling
We are not some big Corp. That can
afford to offer free shipping or free boxes and tape. Every time you purchase a
item from us. A true motorhead pulls the part, wraps it for safe shipping and
boxes the part.
This all cost money. so we use terms like box
rate A, B, or C
This is because some things are easy to ship and
other take a lot of time.
We charge a handling fee accordingly.
Between 2.50 and 25.00 (large bulky items)
As we work to make our store front better, we will
be offering other shipping companies
