looks clean, would love to see the engine bay

So in advance of considering an engine swap, I'm looking at either wilwoods or stoptech's. I know Troy has a stoptech kit designed for 280zx struts but I'm unclear on whether it will work with my setup. Same goes for the T3 Wilwood kit. Any thoughts>?

I should be there as well.

I know there are a few companies out there making cv axle conversion kits for the 510 and I'm wondering if their is a hierarchy of who is making the best kit. I was reading that one person had an issue with the Ermish kit but it's hard to tell if that's a design issue or something else. I know the datsunrestomods kit is popular but I don't know how it compares to futofab or zcargarage.

I should have specified I was looking at LSD's exclusively.

Right now I'm running a stock datsun diff in my 1970 510. It's clunking a bit and I've been thinking about upgrading to either a subaru r160 or R180. I'm thinking for now that I'd like to run a 4.11 ratio which the r180 never came in but wondering if I'm going to be limited down the road with an R160 diff if I decide to do an engine swap to something with closer to 200hp+ I'm certainly not launching my 510 or drag racing but I also don't want to worry about the rear diff being a time bomb with an engine swap down the road. At what hp/torque do the r160 diffs start to fail, what numbers can the r180 withstand? It seems like it would be quite expensive to get gears for an R180 diff to swap it to 4.11 so each diff comes with compromises. Ultimate goal would be to do a cv conversion too and I'd really like to avoid buying an r160 now, just to upgrade to an R180 in a year or so.

Let me know what angles you want or if it's helpful I can take a video.

Any idea what kind of numbers your old lz23 made?

It works really well, super high quality and the fit is on point. I can take photos of it if you want.

Do you know what ratios the STI R180's came in? I'm fairly convinced I want to go 4.11 LSD if possible. It seems like I can get an R160 diff and get stub axles but not the full cv axle conversion, or I can try and find an R180 diff in order to get the full Datsun Restomod kit but it's unclear whether the R180 ever came in 4.11

Is there a difference between the r180 subaru diff I posted and an STI R180 diff? I want to get the datsunrestomod cv axle kit and I'm trying to confirm it will work with that diff. I don't know how to check if that diff is a clip in style differential or requires the stub axles to be bolted in.

So if I wanted to get this diff: https://www.ebay.com/itm/234177237749?hash=item36860d12f5:g:uyQAAOSwcEdhN-xg , I would just need to get the 510 style stub axles with the snap ring? Seems to me that it's probably easier to get newer stub axles rather then getting two rear diffs and swapping the LSD carrier unit into the 4.11 open diff? Just trying to understand the pros and cons and where to actually find parts so I buy what I need and not parts I can't end up using. Is there any advantages to running CV axles over stock 510 u-joints when I just have an L20B? Down the road I may decide to build or swap an engine but right now I'm not pushing any crazy HP.

I ended up getting the BRE cover.

I'm in the market for a new rear differential for my 1970 510. Currently running an L20B with dual mikuni 40's. No immediate plans to upgrade the engine. Current diff is clunking so I'm in the market for a lsd diff and thinking 4.11 gears. I know lsd 4.11 diffs are rare so I'm wondering if I'm better off getting a 3.7 LSD and swapping the core into a 4.11 diff? Also I see a lot of diffs on ebay but it's not quite clear what it would take to fit it up to my 510: https://www.ebay.com/itm/234135521644?epid=1130916661&hash=item368390896c%3Ag%3AL5cAAOSwp45hFZOI&fbclid=IwAR36v95Znsab9mXTR_LW-ojFUjcj0bi3PpZ45pPwzyMcY0Iz2_1PAcpiW9c Should I be looking at a ratio other then 4.11? Plan is to covert to cv axle kit.
