I have a set of bbc gen4's going into a 01 38 lightning does anyone have suggestions on housings or coupler part numbers or have any for sale? I am planning on machining the flywheels for an inside starter ring gear but my engines are getting rebalanced with the new pistons if there is a better way... Thanks, Drew

what drives does your lightning have?

They are Imco extreme sc upper and lowers. Are they the same spline as xr's?

http://www.michiganmotorz.com/mercru...ler-p-562.html Looks like the best number available for a coupler 861523a7. The 861523a9 looks weak aluminum and the 861523a11 seems to be the same. Any thoughts?

yes,i recomend calling teague custom marine,they will fix you up.
