offroading I.T.R.O 18 yrs mostly in scotland,where the hills are steep and the water is F**KING cold.
Yep rolls plenty,my own cages no problems at all,i have built 25+ GRP "n " subaru cages from scratch a few involed in Heavy Fast rolls into tree's, walls and down big drops and all crews involved walked away!!!!
engine swaps errrrrrrrrrrrr not enough fingers to count,cozzy powerd 205 pug, TT (300bhp) engined vw camper van,civic vtec in a mini.
Scratch built cars yep how about a pilbeam SR2 le man 24hr car from start to finish.
Axles swaps yep a few suzi jeeps onto toyota units.
Not being funny here but putting a set of mog axles on a motor IS'NT the be all and end all!!!
If you want to get techy make your own indepedent suspension that involes alot more thought.
That said from what i have seen of your motor it,s looking pretty dam good!!!!
