RT40 Lowering Blocks Pin Size

[Just1n_mc]

So i'm trying to buy some lowering blocks for my 40 but of course no-one lists them anymore. Everywhere I ring ask me the same question: "What size is the Locating Pin?" So my question to you knowledgeable folk is: Can anyone tell me the size of the pin so I can buy the right blocks??

Any help would be much appreciated as I can't get to the car at the moment to check them myself and a search has come up with donuts.

Cheers, Justin.

I just ordered corona lowering blocks of egay and ground the post down to suit.
I think they came with 25mm posts was a easy fix, plus had to bend the u bolts a little more to suit the narrower axle housing
I used 2" blocks and they were mint

Turns out that they are a 19mm in a 70 model...

Yeah RT80-81 are the same.RT40's dont run a T series diff they are an oddball D series or something found this out many years ago when I tried putting a T series from a RT 104.They dont fit the housing.

I just fitted 4" blocks to my RT40 from a hilux with 19mm posts and fiited sweet with a small amount of modification.







Holden/Isuzu Gemini front springs fit RT40s
Standard Gemini springs give a 1 1/2" drop
Lowered Gemini springs will give 1 1/2" + the listed drop for the springs you get.

Im looking at some some super low Gemini springs so will give a good drop hopefully about the same as my cut front springs I have at the moment hahaha
