I have a 68 floorpan and want to add IRS suspension. I see that you can get conversion kits (Bracket) and it also means modifying the frame horns to accommodate the cv joints.
Is it possible to unstitch the irs rear end complete and attach to the 68 floorpan

Don't want to add torsion bar front framehead to the later chassis. Could run into too many problems with ADR rules

If this conversion can be done as requested any ideas on how to get all the dimensions and alignment correct

all the information is available here, very detailed.

Thanks for the link vwo60
However the info is mainly on conversions with the bracket welded in or the bus bolt on conversions
I should have mentioned that I have a beetle and want to do a transplant of the complete irs rear end onto the swing axle pan. Do not want to use any of the swing axle parts
I dont know if this can be done but would like to get an exploded view of the swing axle and irs rear ends to see if i can stitch the irs rear end on.
Has any body done this and was it acceptable for engineers to pass

Why are you going to all that trouble and expense?

I have a complete rolling 73 L bug rear suspension and also a bare rear end with arms in Taree if interested.

The quickest and best way is to weld the brackets on to the torsion bar housings, i think you are making work for yourself. the only difference beween the two rear ends are the brackets, if you had a earlier pan then you would run into issues with the shock towers requiring clearencing for the spring plates.

As above. 2 main thing need to change for IRS conversion. 1. Weld in brackets need to be added to the existing chassis. 2. Heat the frame horns where the CVs sit and bash/bend/hammer/carefully Clarence enough Clarence for the CVs to rotate freely. Then bolt in IRS Box and IRS spring plates and longer torsion arms in and diagonal arms. DONE!

The brackets will effect your rear geometry so they need to be put in the right angle etc... Get this part right.

Ps you can see my conversion pics here, not a how to sorry.

Thanks everyone for your ideas. I think you may have convinced me to go with the brackets
Where can I hire a set of jigs for this. I am in the outer eastern suburbs of Melbourne

Give Nils on here a PM as I borrowed a Jig he'd made from an IRS rear end.

Otherwise you'll have to find a local VW owner that you can borrow their Bug to make the jig on.
