Just give the car and diff to a shop and tell him what you want and they'll measure it all up etc. 1. Less #OOPS#ing around 2. 99% chance of a near perfect fit 3.warranty 4. Easier 5. More chance of it being done properly the first time instead of u missing something/ or not doing something right.
Mate u won't do it in one piece.. And still look presentable!!Especially with that #OOPS# quick grip stuff. You'll need to make it into a few panels..
To cover cracks either a layer of bog or even a layer of foam.. Either way it's gonna be hard to do it in one piece..
I worked as a trimmer in probably the best or one of the few custom modification work shops in Australia and learnt a lot.. Trimming isn't as easy as putting glue down on both surfaces and then sticking them together.. There's a #OOPS#load more to it
