wayno Posted June 13, 2014 Report Share Posted June 13, 2014 It looks like a 520/521 frame with the shock tower cut off, and I have done this conversion, as far as I know you will not be able to align this without modifying the upper or lower control arms, also castor is going to be an issue unless you know what to do. If it was a bolt on, everyone would do it, but it's not a bolt on, and there are issues to contend with, I should know, I did this 10 years ago, the first 2 years were fun, not knowing when the driverside upper control arm bolts are going to break is always fun, especially when the frontend drops out from under you when you just touch the brakes. Do yourself a favor, drill out the upper control arm mount bolt holes and tap them for the 720 mount bolts, the 520/521 mount bolts cannot take the stress. If you have any issues with alignment or driving, let me know, I have done all this, I won't do it again, I just mount the 520/521 cab on the 720 frame now. 1 Quote Link to comment
140ypower Posted June 13, 2014 Author Report Share Posted June 13, 2014 Nice front suspension improvement. Why are you putting a heavy axle in back? Unsprung weight degrades smooth ride and handling. because in Finland the shaft may only be replaced to match the original load-bearing capacity and 521 axle weight is 1300kg :( i think before that nissan s14 rear...

The 720 mount bolts are larger/stronger than the 520/521 bolts, so when you used the 521 bolts to hold the 720 upper control arms in place on your 520/521 frame, what did you do to take the slop out, did you sleeve the holes?
