4-speed to bellhousing bolt size

Does anyone know the thread size and length for the 4 bolts that bolt the 4-speed to the bellhousing on a 455?

Thanks

 

1/2" x 1.5" I think , its been a while.

 

ok 1.5" is the length?

 

I have a set of stainless steel replacements if you like $12 shipped. They are the correct size just shiney!!:TU:

 

Here`s the thing,i would buy a set off you but because of the Tremec 5-speed i have very little room and i need to purchase a set of Allen head bolts thats the reason i`m asking what size they were,so 1.5" will do?

Thanks

 

these are 1.75 so I am sure 1.5 willl work too

 

Good point, I need to do the same, need a nice allen head to fit in there.
