70' 8-lug to 75' 5-lug

guys, does anyone have any pictures of this conversion or info on the conversion? other that changing the complete front cradle really need to know the mix and match of parts to make this conversion without ending up with a huge headache and 2 trucks ripped apart in the driveway. i helped swap a 77' cradle into a 65' 20 years ago and it was quite the job. i'm limited in the "crawling around" area due to health issues. thanks.

you should be able to just swap out the a arms and spindals i don't think you have to swap the craddle

i put 76 ball joints and 76 spindals in my 63 a arms and used the 76 steering stuff

not sure about the 3/4 ton ball joints but you might be able to just swap spindals

I'VE SWAPPED SEVERAL FRONTEND ASSY'S OUT OF MID TO LATE SEVENTYS TRUCKS INTO 67-70s. I'VE NEVER DONE ONE ON A 3/4 TON, BUT THE FRAMES ARE THE SAME OUTSIDE DIMENTIONS AS A 1/2 TON, ONLY ABOUT TWICE AS THICK. (MATTER OF FACT I PUT A 75 ASSY. IN A 69) I CAN SWAP ONE IN ABOUT A THIRD OF THE TIME IT TAKES ME TO CHANGE BALL JOINTS & TIE ROD ENDS IN ONE. IF YOU'VE GOT A DONOR TRUCK WITH GOOD USABLE PIECES.. GO FOR IT. G.M. MADE SEVERAL SCRILLION OF THESE BETWEEN 73 & 86 . JOHN
