[DeTomaso] Engine cover

I might suggest that if a person can't take a flat bar of mild steel, lay out a bunch of holes, tap it (to any size they like), and then cut the bar into squares with a hacksaw, maybe they should just take their car to a specialist....  OR.....  just buy the nuts from one of our local vendors?

I am happy to mail this piece of stock off to you or to your buddy....

The stock is 1/8" thick, by 1/2" wide - the length is immaterial.

I agree with Larry - this project is a no brainer.  It is also possibly a good learning opportunity for VERY BASIC fabrication.  You get a lot of pride out of successfully completing a project yourself.

Larry,

Not everybody is fortunate enough to have the wherewithal to cut steel, and drill and two holes. That's why I volunteered to help the fellow out. 

I don't have an original to copy and don't have ready access to the cavity where it needs to go. All I need are the dimensions and I can go from there. 

Or since you have already done it, and have access to a car in a much better state of dismantlement to provide the necessary data, maybe YOU could volunteer your services to him?

And my 'simple metric nuts' observation was base on direct experience--that is what the 1971 cars used. The later cars use bigger captive nuts. How much bigger I don't know.
