anchor plates and gas tanks ?

[viking427]

Have a broken anchor plate (4 hole plate that holds the axle tube onto the leaf spring) on passenger rear of a 69 K5 Blazer, anyone know what years interchange with it so we can begin our hunt. LMC and other catalogs don't even list them. One spring distributor said 67-87 are the same on GM 1/2 ton (3" tube) "K" series 4wd, but I thought I'd better confirm here with the experts Also, all the new replacement gas tanks (metal & poly) just have 2" stub tubes for filling, where the original fills had a nice formed "S" metal tube leading out from the tank. Do they really expect us to cut/weld our old S tubes back on there, or just install a longer rubber hose ? WhatRy'all doing about this on new tanks ? Thanks
