    I'm on the lookout for a set of leaf spring pivots (I think P & J calls them t-bolts) that will accept a 2" spring. Every one I find is for 1 3/4" spring. A more capable guy with more tools on hand could whip these up but that guy ain't me at the moment.

    I checked P & J, Posies, Speedway, and a couple others including a general internet search. No dice... if anyone can point me in the right direction I'd appreciate it. Also, if this is the wrong place to post I can fix that. swtbolt 1.jpg swtbolt 2.jpg

    The lower one looks cast. A huge no-no. Definitely need to be forged or very well fabricated from steel pieces.

    Oddly enough, they look very similar to Morris Minor trunnion pivot brackets.....

    I would doubt that the lower fitting is cast, it's probably a forging.

    A heavy 1/8" thick washer on each end would let it accept a 2" shackle.
     
  6. Yep, pretty wide parting line for a casting.

    The second one looks like Speedway. Bought some there a few years ago.

    Speedway advertised those as "investment cast" stainless steel . The upper iteration is very simple to make . You could grind an 1/8" off the spring eyes without problems .

    I think I'd sooner go thick washer/fabricated spacer than removing material from anything.

    I fabricated similar with thick wall tubing with HT cap screws welded to tubing. A small jig ensured both were identical

    that thought occurred to me but i think i dismissed it as not being ideal for some reason. it may come to it though.

    i appreciate the comments, all. i'd still like to come up with a pivot in the size i need but the washer idea may be the way to go. still, if anyone has a lead, or other thoughts about it, please share.

    Some factory stuff used spacers. I'd do the spacer thing just to be able to use readily available parts.
