Looking into this quickly I will not be able to beat ost rads price on anything they sell.
KGS are selling a clutch puller and fot a high chrome part I cannot compete with that either his engine splitting tool looks good as well.
Really I don’t want to tread on his toes or use his design.
The alternator puller is realistically a bolt with a bar welded on it and ost rad are as cheap as I can go.
That leaves the bearing / oil seal drifts I can make one that will do both jobs for about £20 ish a side.
Thats how it is from here. I have to buy in material and finance making the stuff.
