I have an '88 cradle that's been modified to use rod-end links and SAE 1/2" diameter bolts. Also the knuckles were reamed out, for 1/2" Grade 8 bolts. Getting it from Florida to Iowa might be pricey, though.
I have a complete rebuilt 88 rolling chassie along with all the rest to put it back together. 88 notchy body and an 86 aero body, 5 speed tranny. No motor, that I am looking to part with, email me at Craig.Torgerson@widseth.com if interested I will send you photos. Located in West Central Minnesota Thanks Craig
