the block between the rear axle & the leaf spring measure that block
it should also have a tab/arm off of it to touch the bump stop
if i had a pic id send it but i dont
how big of a lift are you getting?
im running a pro comp 6.5" with 35x13.5x18

I think you have the 2.5 but I dont remember. I think the F350's have the 3.5's

Measure the block between the bottom of the spring pack and the top of the axle. If its an angle block, measure the middle of the block.

without taking pics... i have my axle then a block thats only like 1.5in tall then the bottom of the leaf...? ill have to take pics tomorrow to see. i thought it had a bigger blocks stock.

and im going with a 4in pro comp with 35s

well thats what i was looking at earlier and it was only like 1.5 in ?

maybe this pic will help. my leaf spring sits right on top of this...

im going to see if i cant go out and snap a pic real quick

Thats your spring perch. Its welded directly to your axle (hopefully, lol). You should have a block that sits on top of that and then the spring on top of that.

i think we have a problem... i dont see a block at all

and i think i might already have an add a leaf...?

im def not a spring expert
