Mike,
Don't know if this would help...Older corvettes have IRS with a center section that has no tubes...U-joints go on a flange with 4 bolts...That would kick |removethispart|@$$ in the front and rear..You could mount in the center of the front.The drive shaft would be sidways,but the housing woundn't move..All kinds of things could be done around those center sections...Let me know if you would like some pics..I got a 78 corvette,It has all kinds of mounting holes,Camber bars,leaf springs etc. all bolt to the center..would be a good center...
