Customers highly appreciate the product for its excellent fit, easy installation, and great quality. Many report that it aligns perfectly with a 4-speed Saginaw without protruding, creating ample space for the shifter and linkages. Recognized for its practicality, it effectively stops leaks and is ideal for a speedo cable deletion. The product is not only functional but also aesthetically superior. Despite alternatives being slightly cheaper, customers recommend this product for its superior performance and value.

Trans had a horrible leak from the speedo cable port on my TH350. Going with a GPS speedometer so needed to plug the port anyways. This piece fit PERFECT. Literally a 5 min install from start to finish. Very happy with it and looks great. Well made piece.

I bought this for a 4 speed saginaw. Everything lined up great, it fit in the speedo hole snug and without any leaks. Doesn't protrude any giving tons of space for my shifter and linkages. I'm sure you could save 5 dollars on something else, but it wouldn't look as good or be as easy.
