Chassis Shortening

[OlberJ]

Any bodywork guys on here able to offer some input on the best way to approach this?

I'm going to be shortening this chassis/floor pan by exactly 100mm.



Now I have seen others build a jig which bolts to the hubs and then slides the required amount, post cut. And this is probably the best bet for accuracy but I don't have access to marble flat surfaces etc to build said jig on.

So how would you go about it?

The cut and weld will be a Z cut so there will be strength in there, that's fine. It's just to find out how to best re-align the chassis post cut that i'm looking for if you have any experience of this?

Would a series of angle iron runs welded to the rear section and bolted to the front with holes 100mm further down to relocate to work ok?

It will only be the floor pan and running gear and engine bay that will remain and I plan to make the amendments in the rear footwell.

Any thoughts or links would be appreciated.

You should weld in lots of small box or tube supports like a roll cage before you make your cut this will keep it rigid, but before making the cut take your reference measurement points that you will go back to when realigning. What you putting on it.
