Frontline/Costello Front Suspension

I've got a totally wrecked 1971 MGB with the Frontline/Costello front suspension kit installed. There appears to be no damage to the front suspension...the car was in a rollover.
Would there be any problems in putting this whole package under my 1978 roadster?

I would just swap over the Frontline parts to your crossmember.

Are you considering magnafluxing the ferrous parts and Zygloing the aluminum ones. (I'm no expert...just curious to understand the question.)

I'd strongly prefer the chrome bumper crossmember for lower ride height... though making that fit will be a pain: oil pan clearance, steering racks mount differently, etc.

Curtis and Jim:
I came by this car as salvage. It was owned by a friend who wrote it off last year. In looking at the damage and hearing my friends description of the accident, I think there will not be any damage to the front suspension. However, I plan to thoroughly inspect each part and can Magnaflux and Zyglo the components at a friend's shop.
I too would like the chrome bumper crossmember but was concerned about the interference issues you mention. I have the Rover 3.5 conversion. Perhaps Jim's suggestion to just transfer the Frontline parts to my crossmember is the best choice.
The rear suspension is toast..................both the Doug Jackson composite springs are cracked. The Quaife LSD seems to be OK but I'm not sure I want to run a 3:07 ratio with my T5 and 0.63 OD. The wrecked car has a GM 700R4 that is modified to shift sequentially as a manual with a manually engaged converter lockup.

I'm pretty sure you don't want want to do that, Phil, unless you are running a stump puller engine like the MG Roadmaster. :)

That Quaife will fit in the rearend of your car, unless you are not still using the stock Salisbury. I don't remember.

Some of us do remember the car, Supernatural, & Jean Gagne (who was at Indy V8 2015).

Rear leaf springs cracked, huh? That could have been before or after he went off the road. I wouldn't want to hazard a guess as to which it was and I doubt you would either Phil.

The composite rear springs do not hold up without anti-tramp (traction) bars.

If I remember right, Phil has a narrowed 3.45 Ford 7.5. I think he was asking about swapping the entire MGB axle with the 3.07. If it had the 3.31 gears it would be tempting.

Right. I would sell the Quaife & buy a real posi for that Ford rear, then.
