those that have builded a frontend?????

Here is a more affordable option I just stumbled on from Martz Chassis. It's a "weld-in" cross-member and includes everything to get back on the road including brakes for $3050. Does not include a sway bar, not sure about motor mounts. I've read good things about guys that have put Martz stuff in Novas.

I just read through the installation. No motor mounts included, but the kit seems complete to help you with the install.
