    The 620-z

    The front end was next on the agenda as i began to turn my attention to the body work, Getting parts in the UK is quite difficult and the inner wings of the truck and the front panel was in bad shape. I was able to get a replacement front panel and being that I planned to fit a V6 I decided it would be best to have a removable front clip. And so began the cutting. I first made side supports and had some laser cut components made to suit. I then removed the front panel and the inner wings and began fitting the new front panel. Once that was complete I could get an idea of how the panels would fit.

    Short post on modifying a rear MX-5 subframe to take a 350Z diff as I didnt get many pictures. The 350z diff s quite a simple item to mount, with two mounting bushes up from and one rear pin that goes through a bush mounted in the subframe itself. At this point having the subframe mounted to the chassis was important, I had it fixed in place when i found a fixed 90 degree angle between the frame and the diff input flange. I then centred the diff input flange to the chassis and also the output drive shaft flanges needed to be located correctly and in line with the rear knuckle so that the drive shaft would not foul the rear suspension upright. For the front I made the new box section mount that I wanted to weld to the MX5 subframe, I also made a rear mount that would be fixed at the back of the subframe. I fixed the new mounts to the diff and got it into position within the subframe and measured several times before tacking the mounts into place. i then removed and fully welded. Here are some pics.

    I used my wedding as a deadline also. If im honest im not sure if i was a bit over ambitious or naive, what was 3-4 hrs work on weekday evenings only in the last 4 months became 4-7 every evening and almost every weekend solid. It near killed me in the final month haha

    It was about 10 months. I work 9 to 5 so only had the evenings and the weekends i was willing to give up.

    Looking back I am just happy after some extensive shake downs the design and welding has held up perfect. although some changes have since been made

    Next up i turned my attention to the rear of the chassis and began to consider how I would mount the rear subframe. For the rear thanks to the available space I knew i wanted to keep it as a removable bolt on item for ease of maintenance. Upon measuring I found that the rear sub-frame would sit perfectly between the chassis rails. It seemed all to easy on paper but with a little measuring it became quite obvious that the rails would cause issue with the upper rear wishbone and also the coilover itself. I found a few versions people had done by notching parts around the vital components but that was not for me so I knew some drastic chassis cutting was needed. Which is what follows. First I removed every unnecessary bracket next I made up the ideal chassis section that will need to replace what is existing. Once that was made I could actually begin to weld the item into the rear of the chassis without making any cuts to the existing chassis legs. This plus a number of ugly braces welded in were perfect to prevent the chassis from moving when cuts were made. As you can see this allowed me to do one side at a time completing it in two halveds. Once the chassis rails were complete I could move to complete some more extensive bracing. And finally back down on all 4 wheels with twin wishbone independent suspension :)

    Thanks, I definitely do my best to keep it some what unique along the build, I will see if i can get another couple more posts up today

    I am indeed based in the UK, The truck is complete now. I will slowly get updates onto here, all my pictures are ready to post so just need to get them onto here. may do a batch a day or something

    After completing the lower of the subframe jig I had both a level point to take measurements off and something substantial to weld into position, So I began modifying the chassis to accept its new front frame. Next up was to create top mounts for the suspension uprights. I had saved the top mounts cut from the MX5 so that I could bolt to two holes pre drilled in the top of the upper arm mount so that I could achieve alignment. And then she was back down on her own feet up front

    Next up was a big step. I decided i would commit to the MX-5 suspension but simply welding in a front sub-frame from an MX-5 as I had seen some examples of would not be something I want to do. they are far to ugly, bulky, rusty, flimsy and fairly impracticable where space is concerned for what I would like to do. So with that in mid It was clear I would fabricate something of my own using the MX-5 subframe as a basis and transfer over the desired mounting points to achieve the desired geometry So I began by making a subframe jig.... Once that was complete I began making my own subframe

    The truck had not moved in 30+ years and once home a good clean was needed, The car was like a time capsule inside containing everything that was in it on the last day it was used, news papers, documentation, money, even the recipt for the Ford pickup that inevitably replaced the datsun and saw it parked up in storage. Next of course came the breakdown and after a good clean I began stripping her down. the brake fluid had seen better days
