I think it was about £100 to do the ABF bottom end im building at the moment (got a few other bits done at the same time so not 100% sure) but we didnt get much weight taken off so maybe a bit more for what your after. Try 01524 791507 and speak to Mr Gardiner, he was pretty cheap for all of the work we had done. I think the company name is Hi Tech Racing but I would think hes too old school for a website.
