George,

I checked the diameter of the 12A bolts I have......The threads were about .009 thousands

proud of the bolt shank diameter........Probably caused when the threads were rolled...IMHO

Kelly,

I found a local Company who does rolled threads, but will only do a minimum of 16, I said I can handle that - but I don't know whether to cut down 12 A bolts, cut down 13B bolts or get some high tensile rod and make new ones.

Any suggestions on the best way to go?

Someone suggested the 13B's are necked-down, I will have to check on this.

There is also the suggestion of threading both ends, in a stud configuration. This may not be necessary if using 12A bolts, but does allow for some variation in length

George,

Bill is correct of course about rolled threads being the way to go but here

in the middle of the USA availability and affordability are a problem.......I do

not have my 12A bolts in front of me at the moment and will have to double

check if the threads are proud of the bolt diameter on the ones I have.........

Kelly,

If someone can find how long the bolts need to be I can see if we can find a source to mail order them. ARP fasteners are a high quality automotive source. WWW.ARP-bolts.com

We should check to see if they will make studs to replace the 13B bolts.
