Thanks datzenmike - but the reference to two chassis is that they are both long base ones. SWB very very uncommon here in NZ. Thanks for the info about the tray mounts. So list: Remove 9.5 inches from straight part of chassis just rear of cab & reweld Shorten drive shaft 9.5 inches Shorten brake cable Shorten brake lines Swap fuel tanks + shorten fuel lines shorten or (coil wiring) move front tray mounts back 9.5 inches?

You're such a hoarder! (I thought the exact same thing!) same name on oldschool. Have rigged up someone to do the welding - just need a ute now and confirmation I can get a short wellside from Thailand.

Hmm, it's looking like not if but when! How long should the sleeve be? Good idea about the plug welds, def the way to do it. I spoke to Sam, he mentioned the non certed front disc conversion, and possible sus weld on a cab mount.He said that was about it - but that 3k seems pretty expensive but I haven't seen any cheaper (beside the fully dereged one for $500) - I don't have lotto luck like you. The red one is ok, don't like the shaved look, but the sr is a distinct advantage! This just came up for good parts http://www.trademe.co.nz/Browse/Listing.aspx?id=690972775&permanent=0 OK I need a 620 in good condition to do this mod.

Hey Nah not on NZDatsun Yeah, I don't have a live example to view so have just been looking online for pics of the chassis etc and comparing the two. The LWB has what looks to be a straight bit of box chassis directly behind the cab, which is where the 9.5 inches would be cut from, and by the time it was cut, the chassis rail would still meet on straight chassis rail. From there, wellside mounts would probably need to be moved to suit the swb? Pic below - from there, drive shaft would need to be shortened, wiring, brake hoses, handbrake cable, what else? I'm wondering what the best way to cut & weld the chassis would be, an stair like fashion e.g. ¯|_ or a fish tail or what? But either way I agree that a plate would need to be also welded on the inside. I agree about grinding the welds so Mr VTNZ never sees them - should be pretty easy. My only problem, I'd need someone to do the welding. Am weighing up whether to invest in the blue one on Trademe which use to belong to Sam on Oldschool. My drawings:

Thanks everyone for your replies. Still searching.

People do it on other trucks quite often - what would be involved?

Bart - you little ripper on that wellside deal. I was looking at it too and trying to come up with a plan! Good job man, glad it's gone to an enthusiast. In NZ all I have ever seen for sale are LWB chassis's. What would be involved with shortening a lwb 620 chassis to swb? Has anyone completed such a project on here (probably not as most other places have plentiful supply of both?) I know they do it quite a bit with other trucks but curious if there is a specific example completed for a 620. Cheers Flip

Thank you. Rats - it's a LWB model and the wellside I could acquire is SWB, bummer, wellsides are rare as hens teeth here in NZ. Appreciate the help

Thank you - that helped immensely. Currently it only has a flatdeck (non kingcab) so wanted to know regarding the measurements for wheelbase stamped on the plate as I can source a SWB wellside. And yeah from NZ (so Aussie close enough!)

Hi I'm thinking of buying a 620 which has been used as a farm vehicle I've never owned a 620 before, just a B110 Want to know of common things to look for e.g common places for rust, particular points in the chassis for rust, things that will be a pain to replace, vs general rust/sheetmetal repair. Also - on the plate under the bonnet - what are the measurements (in mm) for short vs long wheel base? Thanks
