Your welcome , I have had this book since 1980 or somewhere around
then , a friend of mine gave it to me , he had just finished building an old
signet and I was building a 68 notchback at the time. I still remember
when he put it in my hands he said "read this whole book Wheels and you will be smart". Now if I could only remember what I read yesterday.LOL.
Cheers , pic of the book did not load . It is an old Direct Connection Racing Manual
printed 1976.
