yeah they certainly look the goods, i havent really had a chance to do much with the ones in the FX yet, other than when installed them i put them on full soft then full hard and jumped on the rear of the car! :)

Bit more progress, after re-aligning all the front guard/bonnet/grille attachment points and probably from some tweaks i did to the turbo manifold the exhaust exit in the guard wasnt in the right spot, so i did a combination of enlarging part of the guard hole and cutting and re-attaching the last bend in the exhaust pipe and got it back out the hole! It needs some minor trimming in a few spots but its good enough for the time being!

When i made the four link diagonal adjustment bar i cut it slightly too short, and i wasnt really happy with the amount of threads in the bar on the rose joints, so i hatched a plan to lengthen the bar and also added a hex section to allow a spanner on for adjusting.

So i cut the bar in the centre...

Then machined up a bit of hex bar to go inside it ...

And glued it all back together!

I also just got a notification that my front coil over shocks are in the mail so thats a bit exciting! i highly doubt i'll see them before the weekend but i'd say definitely next week some time!

Just a wild guess ... :roll:

Color!

If you look at that cold rolled mild steel hex bar stock it will be a bit duller in tone then the 4130, chromium is a lustrous material.

But I must admit I really am guessing a bit for I really can't see the end cut of the tube so well, not to mention the white of the background tossing in a curve ball ...

A little Tap Magic would do wonders on the finish of them cuts and add life to the cutter.

You glue it with er70 mig ??

i wasnt too stressed about the finish of the cuts as they were going into the tube, i was more concerned on a nice snug fit :)

yeah was just mig welded.

Yup, knew that from the spiral running the carriage back ;) ... was just pushing Tap Magic!
No affiliation, just have used it for 50 years, love that stuff, nothing better, it's Magic!

Did you pre heat the 4130 to 4-500F, then slow cool it ??
Those two will heat and cool differently possibly causing cold joining and or cracking.
Honestly, I don't think you'll have an issue, many have done it ... it's just ""more"" proper.
