BJ4 (non-WE) chassis replacement options

[colmo]

Hello all,

I've just acquired a rather battered BJ4 (non-WE) and was disappointed to find the main chassis was tweaked. The previous owner must have known about it, because the shocks had been adjusted to compensate.

First of all, is this likely to be an issue? I'll be testing the car later, but with no frame of reference, is this likely to hurt the handling?

If it is better to get a replacement, what are the options? I know I can get one directly from JConcepts, though I am unsure how much shipping and customs (USA>UK) will increase the price by. Are there any other makers of compatible chassis?

I've also considering making one out of G10 sheets (3.2mm think) - the car is for use on polished wood, so a little extra flex is no bad thing to improve grip.

Finally, if anyone has one going spare, let me know.
