Hood springs....adjustable or no?

[McCoyAZ]

I bought a brand new set of hinges and springs from Tuckers that were to be used on my 64.

I had a body shop install them, using a 61 hood and they are so weak they hardly hold the hood open.

Is there an adjustment somehow to make the hood open and stay up?

and speaking of Tuckers....

I also bought a pre made wiring harness for the signal lights. The bulb holders don't fit all the way into the sockets on the light cans.

Or am I doing something the wrong way? Is there a trick to getting them in all the way so they will stay in the cans?
