motavated Posted September 5, 2009 Report Share Posted September 5, 2009 He lives close to were I live. They are hard to find. Have your tried hardbody or 720 bolts? Just buy the bolts from a nissan dealer really! How much would they cost? 20 a pair$ new? Link to comment
a.d._510_n_ok Posted September 5, 2009 Report Share Posted September 5, 2009 On my '80 510 the original A arm bolts were 10mm shafts, grade 8.9 and were pretty loose in the A-arm bushings. I replaced them with 1996 Pontiac Grand Prix engine mounting bolts that were 3/8 shaft (took up the slack in the bushing but still moved very freely) that were grade 10.9. I have no clue what size they are on a 620 but if they are a 10mm upgrades are as close as the top engine brackes/mounts on a GM 3.1 V6. Link to comment
MikeRL411 Posted September 5, 2009 Report Share Posted September 5, 2009 Control arm bolts are critical to safety. If you can't get them through your dealer, go to http://www.mcmaster.com. This is the website for McMaster-Carr, the best, in my opinion, supplier of real certified SAE and Metric bolts and nuts, not the counterfeit crap that sneaks onto the shelves of corner hardware stores no matter how hard they try to exclude the crap. I have stopped by their warehouse store in the San Fernando valley and bought fully certified and lot traced bolts for a spacecraft awaiting launch at Vandenberg AFB, you can trust their products! By the way, they have a terrific catalogue. Link to comment
fivetenzen Posted September 6, 2009 Report Share Posted September 6, 2009 hey- I went to take t/c rods off today and 78 and 79 are different - take alook and tell me what is under your truck - does it have one bolt under the control arm, going to a little l bracket or 79 has it where there are 2 bolts holding it on to the control arm underneath. - let me know - and what bolts are you looking for ?

SHADY280 Posted September 6, 2009 Author Report Share Posted September 6, 2009 the bolts go thru the control arm bushing that is in the frame, on one end a 19mm nut, at the other it is large and is indexable to match up to the torsion rod arm. the 2 smaller bolts hold the torsion arm to the control arm. you must remove/ pull back the torsion arm to get these out. ill get som pix later for those who can help. thanks guys Link to comment
