Cylinder Head U20
Datsun Roadster 671/2 - 70 U20 Engine Fastener ADD ON Kit
U20 Engine fastener kit - Head stud, rod bolt kit, 4 - small end bushings w/ 2 - ultra lube. When rebuilding your motor add this kit on. Protect your investment. Don't use 50 year old fasteners on your expensive rebuild! NOTE: Small end bushings are included as the installation of the new rod bolts requires re-sizing the rod on the big end and it is prudent to also do the small end during rebuilding especially if you are installing new pistons.
