First let me state unequivocably that BMR weld on LCA relocation brackets do not fit on a Moser 12 bolt. Perhaps they can be made to fit, but they do not out of the box.

Yeah, I know Spohn brackets are the only ones made for the Moser 12 bolt, but I read on here that the BMR brackets would fit and they were less expensive.

Small digression - these things are way overpriced. I think you could take a drawing to your local machine shop and get a set made for $85. Now back to your regularly scheduled rant ...

I've worked in a machine shop and as a mechanical engineer. A relocation bracket is a relocation bracket. Unless you blow the hole locations or something like that there is no difference. The key here is size issues. I've read lots and lots of posts today about reloc brackets (including one which argued that G2 brackets will perform better than BMR) and found more than one which said they don't fit and one who said it was 30 seconds work with a dremel to make them fit. I don't think I could make them fit with 30 _minutes_ of work with a die grinder. Having never been under my Z before, the pictures on the web sites didn't make much sense and I had no feel for how they installed. Now I do ...There are three problems - the BMR brackets are too narrow to fit over the Moser LCA mounts. A BFH helps here. Part of the BMR bracket interfers with weld on the Moser. That I can grind off. Lastly, the back, or closed side, of the BMR brackets hits the back of the Moser LCA bracket forcing the BMR to rotate forward, thus changing the needed LCA length unless you want the rear end to move back.

My first thought is to sell them and buy the Spohns, but I have also read many stories today about axles moving with reloc bracket install. So, maybe I would be better of to hack the BMRs until they fit, or getting some strap iron and making my own. In any case it is going to be a bitch to try to get the holes arranged in an arc that matches LCA travel and get both sides arranged the same. Now I wish I had bought adjustable LCAs.

Well, that is my horror story for the day. Hope you enjoyed it and learned not to make the same mistake.

 

I had no problems installing my BMR weld ons on my Moser. I installed my brackets and rear aroun 4/01, maybe the design (of the relo brackets or Mosers LCA mount) has changed since then.

 

Maybe so. It looks like I can make them fit with some work. I did a little math and it looks like, assuming a horizontal LCA 29.25" long, the second hole should be 0.100" ahead of the first one and the third should be 0.230" ahead of the first one. I've seen lots of post with arguments about how to install, so that may help.

 

Critter,

I had Global West LCA's on my 10 bolt and when I went to the Moser 12 bolt they wouldn't fit so we went and got bought some iron and had them fabricated using the GW's as a pattern. Works fine, I still cut high 1.5 to low 1.6 60ft's but it was a PITA !!!
