Leaf Spring Eye bolts

[TrshTrk]

I've searched and searched and I can't get a solid answer. I've hit a wall.
I want to have the new eye bolts ready to go.
My dilemma is, The window of time I have on the lift is limited.
Throw the truck on the lift, remove old springs, change to the new leaf springs, flip kit, and get out of the shop. haha
SO, I want to have the new eye bolts ready to go. I won't have time to go to different store trying to match bolts.
I know that theyre going to have to get cut off. I already tried breaking them loose and it was a no go.

I need to know sizes and lengths for the front and back of the leaf spring's eye bolts.


The truck is a 69 gmc 1/2, 2wd, leaf spring truck.

thanks in advance
